20th Century Antiques & Design

Authenticating a piece of 20th century antique furniture starts with a close reading of materials and construction. For Art Deco pieces from the 1920s–1940s, look for precious veneers — Rio rosewood, amboyna burl, Macassar ebony — paired with nickel-plated or chrome bronze hardware. A maker's stamp (Ruhlmann, Leleu, Dominique) or a gallery label on the reverse is a strong indicator of value. For mid-century modern furniture, check for tubular steel or bent-plywood structures, and verify that the joinery is consistent with the claimed period rather than a later reproduction.

The 20th century market is notably accessible: expect to pay from a few dozen pounds for a common decorative object to tens of thousands for a signed masterpiece. 20th century decorative arts — ceramics, art glass, lighting — often offer the best value for new collectors. Always inspect veneer condition, the stability of legs and feet, and whether any restoration work is coherent with the original style.

Documented provenance — an old purchase receipt, an exhibition catalogue, an estate history — significantly increases a piece's value and simplifies any future resale. It is worth comparing with pieces from the 19th century to appreciate the stylistic breaks that define the 20th. Vintage lighting and wall lights from this period also make an excellent and affordable entry point into collecting.
