The clue here was Japan, which I am sure confused many of you, but it is the country with the highest numeracy rate. They did not invent mathematics though, because archaeologists have discovered figures and symbols in ancient Sumeria, which is the south of modern day Iraq. However the Japanese did have a way of doing mathematics which was all their own, it started in the early 1600s and lasted for over two hundred years, when Western ways came along. It used a kind of abacus, a very simple system of rods and beads which was widespread throughout the East and also parts of Russia. We know that it did not start there though, because we have notes by the Greek historian Herodotus about how he had seen Egyptians moving lines of pebbles in order to make calculations, just like they did in Greece.
This card shows a Buddhist Temple in Tokyo and it was issued with chocolates. They are really just thin papers, and they were designed to be stuck in a special album, though they still printed the descriptions on the back. I do not know much about Chocolat Pupier, but their advertising proudly proclaimed them "Le Meilleur Chocolat Francaise" which meanss "The best chocolate in France".
They were based in St. Etienne, and were started in the 1860s by one man, Jean-Louis Pupier. He passed it over to his son in 1895 and his grandsons inherited in 1919.
There seems to be two versions of this set, one like ours, with "Bon Point" at the top, and the other with "Edite par le Chocolat Pupier". Those are almost certainly later, because the backs say, in red, "Nouveau prix de l`album" which means new album price. The albums were three francs and then they went up to five francs. However it looks like the red was added to a card that had the three franc price already, so there could have been three versions, ours, the black backed version with the album price, and the red overprinted version of the black priced cards.
