This has to be up there with the very best of ship signs.
Milchbar Pinguin (Milkbar Penguin) opened in 1964 and was THE place to be in the East German town of Leipzig. Serving, yes you guessed it, milk products. Apparently they had four types of ice cream when it opened, chocolate, vanilla, strawberry and mocha, and the queues were massive, seating up to 5000 (!!!) guests a day. Nowadays it's considerably easier to get a seat and they serve a larger amount of ice creams as well as cake and ice cream sundaes, and pretty decent ones too. The original interior is unfortunately long gone but the signage is still there. And what an absolute beauty it is.
