Poll: I would like to know, if this symbol is well-known outside of Germany? If you recognize its meaning, please don't reveal it in a comment, just vote "Yes", otherwise select "No". And please vote only, if you live outside of Germany. I'm asking for a friend, who told me, the symbol wouldn't be known in foreign coutries. EDIT: With only 13 yes-votes and 285 no-votes, I now added an explantion of the symbol in an answer to this post. Thanks everyone for taking part in the poll! #Poll
