This is a Cinema glass slide, used by the german Winter Aid Work (Winterhilfswerk – WHW) in the winter of 1941/1941: “Zum Sieg der Front, das Opfer der Heimat”.
The condition is very good! These glass slides were used for projection in a cinema before the movie started during the war. The slide was simply put in front of a movieprojector and the image was then shown on the big screen. Comparable to current days commercials before a movies starts, of course this was at the time pure wartime propaganda.
The slide measures approximately 9 x 9 centimers and is in great condition. This is most probably the only one in existence, making it an unique collectorsitem!
Very very rare!!!
