Now I want to open a cheese shop...

Zinken: a symbol used by itinerant travelers who spoke Rotwelsch, which was a beggar's language.

"This zinken told passersby that the owner of the house would give you cheese if you asked."

Thank you! I was looking the other day for European equivalents of (possibly apocryphal) hobo sign.
