na, 1930. An advertising mock up for Kasseler Hafer-Kakao. thin paper pasted onto stiff card. This was a prototype for advertising, selling the cocoa beverage as a children's breakfast essential! The picture and background are a colour printed lithograph, and the text has been painted onto it using watercolour. This design did go into production, and can be seen on wooden oat cocoa boxes from the period. The lithograph has the printed reference "56. J. 6.XX" A little nicking and cracking to the paper image. slight rubbing with a little surface loss, but still an attractive piece. Two pin holes to top edge of card. Kasseler Hafer-Kakao was a product invented in Kassel in 1898. It was a solid oat-cocoa cube which could be dissolved into a drink. At its height, the factory employed 500 people. It closed in 1954. The site and factory is now a museum.
