Petrol & enamel sign auctions: advertising signs, searched at once

Original vintage enamel advertising signs, especially petrol, oil and motoring brand pin-badge or shaped examples with strong colour and no restoration, sell for genuinely serious money, and condition, rarity of the brand mark and whether a sign has been repainted or is a modern reproduction all drive value far more than size alone.

Why enamel sign lots get missed

General collectables sellers sometimes list a genuine vintage enamel sign simply as "old advertising sign" without naming the brand or noting original condition, so a rare, unrestored example can sit unrecognised inside an ordinary-looking listing.

One search across every platform

Auction Bid Assistant's free browser extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay. Search "enamel sign," a brand name, or "petrol sign" generally and results return across all of them, with images, estimates, current bids where shown, and sale countdowns, sorted by platform in tabs.

Real results for "petrol enamel sign": a genuine vintage Wills Star Cigarettes enamel sign referencing Shell, Esso and petrol pump/can imagery, found in one search.

It works by searching from inside your own browser, the same as opening and searching each site yourself, just done in seconds. Nothing is stored on our servers, permissions are minimal, and the extension never places a bid on your behalf.

Alerts: catch a rare mark before it's gone

The best original enamel signs sell within hours of listing, so save a search (a brand, a product, or "enamel sign" generally) and get emailed the moment a new lot matches it, across all covered platforms including eBay, rather than relying on remembering to check each one.

Want to try before installing?

The same search box works on this website with no install at all for eBay, iCollector, LiveAuctionWorld and Featured Auction catalogues, a quick way to see matching sign lots before adding the rest of the platforms via the extension.

Built for how automobilia buyers actually work

Save any lot with one click from search results, export your shortlist as a printable PDF or CSV before a sale, and on the day itself the optional live bridge feeds the auctioneer's asking price into the free bid calculator, so your maximum (with buyer's premium and any applicable taxes included) is always in front of you.
