Enamel advertising signs are the crown jewels of vintage collecting — and the most reproduced. Plenty of “aged” signs were aged last Tuesday. Here's what we look for before a sign earns a place in our pile.
1. Weight and feel
A genuine enamel sign is vitreous enamel fused onto heavy-gauge steel. It should feel substantial — noticeably heavier than a modern tin repro. If it flexes in your hands, walk away.
2. Layered colour
Original signs were built colour by colour, each layer fired separately. Look at an edge or a chip: you should see distinct layers of enamel like strata in rock, sitting slightly proud of each other. Modern printed repros are one flat layer with fake “chips” printed on.
3. Honest rust in honest places
Real signs rust where water sat: bottom edges, around the grommet holes, along mounting points. Rust in strange, decorative places — or perfectly even “distressing” — is a red flag. Nature doesn't do symmetrical.
4. Grommet holes that earned their keep
Fixing holes should show wear from decades on a wall: paint loss, rust halos, slight elongation. Crisp, clean holes on a “1930s” sign mean it never hung anywhere.
5. The back tells the truth
Flip it. Originals usually have a dark, slightly uneven counter-enamel on the back, often with maker stamps. A bright white or bare-metal back is usually a modern pressing.
None of this makes reproductions worthless — a decent repro is honest wall candy at an honest price. The sin is a repro priced like an original. We describe every sign in our signs collection exactly as it is — age, wear, warts and all. That's the deal.
