A sticker from around 1938 reading: 'Jewish shop! Whoever buys here will be photographed' is displayed at an exhibition of antisemitic and racist stickers at the Deutsches Historisches Museum, German Historic Museum, in Berlin, Tuesday, April 19, 2016. One of Germany's main history museums is exhibiting racist and anti-Semitic stickers spanning more than a century, a show that comes as the country worries about racism amid the migrant crisis.
