Antique Advertising Collectables

Identifying a genuine antique advertising piece requires a few key checks. For enamel signs, examine the reverse: an authentic period example typically shows enamel on both faces, slightly irregular edges and a naturally faded tone acquired over decades. Be wary of modern reproductions with oversaturated colours, perfectly uniform edges and an uncoated or reproduction-marked back. Lithographed tin advertising boxes from the early 20th century usually carry a manufacturer's number on the base and show natural oxidation at the seams — signs that are very difficult to fake convincingly.

In terms of budget, the market is remarkably accessible. Expect to pay £25–120 for a branded thermometer or small tin in good condition, £150–700 for a mid-sized enamel sign in fine original state, and several thousand pounds for a large illuminated shop sign or a piece linked to a celebrated graphic artist such as Cassandre or Cappiello. Value depends heavily on brand recognition, graphic quality, format and condition — a sign free of chips or visible restoration can be worth two to three times more than a damaged equivalent.

For promotional figurines and counter display pieces — Michelin's Bibendum, Cusenier, Banania characters — check carefully for crude re-gluings and verify that the original paint colours are consistent throughout. A documented provenance (original invoice, auction catalogue) always strengthens value. Industrial antiques and objects from the world of trade and commerce make a natural and complementary collecting context for advertising memorabilia.
