How to Identify Vintage Furniture Makers' Marks & Labels

Why Furniture Labels and Makers' Marks Matter

When buying vintage mid-century modern furniture, the difference between a confirmed piece by a known maker and an unmarked "in the style of" piece can represent thousands of dollars in value — and significantly greater confidence in authenticity. Furniture makers' marks, labels, and stamps are the primary evidence that a piece is what it's claimed to be.

This guide covers the major label types used by American and Scandinavian MCM furniture manufacturers, where to find them, how to read them, and what to do when a piece has no marking at all.

Types of Furniture Marks and Labels

Furniture makers used several different methods to identify their work, and the type of marking often indicates the era and manufacturer.

Paper labels — The most common form of identification for American furniture from the 1950s–1970s. Paper labels were glued to drawer bottoms, the backs of case pieces, and the undersides of chairs and tables. They are also the most fragile: paper labels often peel, fade, or disappear entirely over decades of use. A missing label does not necessarily mean a piece is not authentic, but a present, intact label is strong confirmation.

Metal tags and plates — Some manufacturers, particularly those producing higher-end work, used stamped or engraved metal tags riveted or screwed to their pieces. Knoll and Herman Miller both used metal manufacturer's tags at various points. These are significantly more durable than paper labels and harder to fake convincingly.

Burned or stamped marks — A wood-burned or ink-stamped mark is typically found on the underside of case pieces, the back of cabinet frames, or inside drawers. Lane Furniture used a date-code stamp system that allows collectors to determine the exact production year of a piece (more on this below).

Branded marks — Like a cattleman's brand, some manufacturers branded their mark directly into wood. Heywood-Wakefield used a branded mark on many of their pieces, typically on the underside of seats or backs of drawer cases.

Woven or sewn labels — Upholstered pieces sometimes have fabric labels sewn into seams or attached to the underside of cushions. Herman Miller and Knoll regularly used woven labels on their upholstered seating.

Where to Look for Furniture Marks

Knowing where manufacturers placed their markings saves significant time when examining a piece. The most common locations are: the underside of drawer bottoms (pull every drawer and check beneath), the back of the furniture frame (particularly on case pieces like credenzas and dressers), the underside of the piece when turned over or tilted (common for chairs and tables), inside cabinet doors on the interior frame rail, on the back of headboards and mirror frames, and sewn into the underside of loose cushions on upholstered pieces.

Reading the Lane Furniture Date Code System

Lane Furniture Company's date code system is one of the most useful identification tools in American MCM collecting. Lane applied a stamped code — typically found on the back of the furniture or on the bottom of a drawer — that encodes the week and year of manufacture.

The format is typically two numbers separated by a dash or space: the first is the week number (1–52) and the second is the last two digits of the year. A stamp reading "8 57" means the piece was made in the 8th week of 1957. A reading of "42 64" means week 42 of 1964. This system makes Lane pieces among the most precisely dateable of all American MCM furniture — an advantage both for collectors and for insurance and estate purposes.

Note that some Lane stamps also include a style/model number, which can be cross-referenced against Lane catalogs to identify the specific collection and design name.

Herman Miller Labels and Tags

Herman Miller labels evolved substantially over the decades. Early 1950s and 1960s Herman Miller pieces typically feature a black-and-white paper label with the company's address in Zeeland, Michigan, and often a designer credit. These labels read "Herman Miller Furniture Company" in some periods and simply "Herman Miller" in others.

George Nelson pieces from Herman Miller frequently include both an HM label and a separate "Nelson/George Nelson Associates" credit. Charles and Ray Eames pieces are identified by the label plus model number (e.g., "ESU," "DCW," "LCW," "Eames Storage Unit"). Matching the model number to documented Herman Miller catalogs is the definitive way to identify Eames pieces.

Later Herman Miller production (from the 1970s onward) typically uses a metal tag or a more modern printed label. The presence of an older paper label format is itself a useful dating tool.

Knoll Labels and Markings

Knoll has been meticulous about labeling its furniture throughout its history, making authentication generally more reliable than many competitors. The primary Knoll label appears in several formats depending on era: early pieces from the 1950s use a Knoll Associates label (the company was called Knoll Associates before becoming simply Knoll International); 1960s–1970s pieces typically read "Knoll International"; contemporary production reads "Knoll."

Designer credits appear on Knoll labels for most major designers. A Platner chair will identify Warren Platner; a Saarinen table will credit Eero Saarinen; a Bertoia piece credits Harry Bertoia. This designer-crediting practice makes Knoll labels among the most informative in the industry.

Woven fabric labels appear on upholstered Knoll pieces, usually sewn into the seat bottom or inside the seat back. Metal tags appear on bases and frames. A verified Knoll label with designer credit and a consistent date-appropriate finish is the gold standard for Knoll authentication.

Heywood-Wakefield Marks

Heywood-Wakefield used a distinctive burned or branded mark, typically reading "Heywood-Wakefield" in a circular or oval format, often accompanied by the word "Genuine" and the specific finish name (Champagne, Wheat, or Honey). The presence of the finish name in the mark is helpful for dating pieces, as finish names changed over time — Champagne was introduced in 1950, and the "Genuine" qualifier was used from the 1950s onward to distinguish the original manufacturer's work from imitators.

Heywood-Wakefield marks are found most commonly on the back of case pieces and on the underside of chairs.

Scandinavian Furniture Marks

Danish and Swedish furniture often carries marks from the furniture maker (the workshop that built it) as well as sometimes the designer. The most important distinction to understand is that in the Danish furniture trade, designers typically sold their designs to multiple manufacturers, and the quality of pieces varies significantly by maker.

Hans Wegner chairs produced by Carl Hansen & Søn carry the Carl Hansen label (a paper or burned mark) along with a model number. The same design produced by PP Møbler carries a PP Møbler label. Both are authentic Wegner designs, but they are made by different manufacturers with potentially different quality levels and date ranges. Always look for the manufacturer's mark separately from the designer's name.

Denmark's Furniture Makers' Control organization issued a quality certification label — a round paper label with "Denmark" and a stylized "F" — that was applied to exports from the 1950s through the 1970s. The presence of this label confirms Danish manufacture and typically indicates export-quality production.

What to Do When There Is No Label

A missing label does not rule out authenticity. Paper labels in particular fall off with age, cleaning, and handling. When a label is absent, authentication relies on construction analysis: joinery methods, wood species and grain matching, hardware styles, drawer construction (secondary woods, drawer bottom attachment methods), and comparison against documented examples in catalogs and reference books.

For high-value pieces, professional furniture authentication services exist that combine physical examination with archival research. For common MCM pieces where authentication is less critical to value, comparing multiple physical features against documented examples is usually sufficient.

Red Flags: Fake and Misleading Labels

As MCM furniture values have risen, so has the incentive to fake labels. Common warning signs include labels that appear unusually clean and well-preserved on a piece that shows significant age elsewhere; labels printed on paper that appears too bright or crisp for the claimed age; labels with modern typography conventions applied to supposedly 1950s–1960s pieces; and labels attached with adhesive that appears newer than the surrounding finish.

When in doubt, cross-reference the label against documented examples in museum collections, auction house records, and specialist reference books. The Herman Miller Archives and the Knoll Archives have both assisted researchers in verifying authentic production records.
