Hitler's picture on Bulgarian billboard

SOFIA, Bulgaria, April 7 (UPI) -- A picture of Adolf Hitler was displayed on a huge billboard in Sofia and immediately prompted the Israeli Embassy to protest to Bulgarian authorities.

The picture of the Nazi leader shown on an advertisement billboard caused outrage in Sofia, the Bulgarian SNA news agency said Tuesday.

An unidentified company put up the advertisement showing a Third Reich stamp with the portrait of Hitler and a slogan "They Speak -- You Listen." The agency offered no further details concerning the incident.
