MONT BLANC Rare Japanese Poster

Well this one is unique. A lovely smaller poster (with accompanying label adding to the provenance) promoting of all things: The Mont Blanc Bakery. There is a bakery that claims to have first introduced Mont Blanc to Japan, aptly named Mont Blanc. As the story goes, the founder, Chimao Sakota, hiked Mont Blanc, the highest mountain in the Alps, and was so proud of his accomplishment (or intrigued by the unique spiralized pastry he had sampled), that he is said to have been the first to bring it to Japan, opening his café in 1933 and introducing the cake in the autumn of 1945. This poster by my estimation would be 1950's / 1960's. It's exquisite and uses the Mont Blanc
