Alex Wyler’s site is mostly in German, but the collection and images speak for themselves. You’ll find old gas tins and signs, gas pumps, air meters, gas stations, and more. Organized by brand (BP, Shell, Esso, Gulf, and Texaco, etc.) and by decade. Wyler does a nice job of interspersing unusual collectibles like shipping crates or service tags in with the rest of the collection.
