The Ampelmännchen is the symbolic person shown on traffic lights at pedestrian crossings in the former DDR (East Germany).
Before the German reunification, the two German states had different forms for the Ampelmännchen, with a generic human figure in West Germany, and a generally male figure wearing a hat in the east.
After the fall of the Berlin Wall, the Ampelmännchen became a popular souvenir item in the tourism business.
This is the postcard I have:
