And it is used only in Pankow (at the start at loeast, as pirates are, several other regions have “stolen” it.) Speaking of stolen, that poster is often stolen as you can read (german) on the linked site.

There is even a follow up with a man and a wombat and “promise kept, first wombat delivered”.
