"As soon as we got them to the restorer, we started taking pictures,
which I sent all over the world, including to the Victoria and Albert
Museum <
http://www.vam.ac.uk/page/p/posters/>, which has a fantastic
poster collection. Some people knew what they were, to the extent that
they knew Japan's national railway had distributed posters in the '30s,
but they had never seen them. Even the curators at the Ogaki Poster
Museum <
http://www.ogaki-postermuseum-japan.com/main.html> in Japan were
stumped. They had heard about them and had some ideas about them, but
they didn't have any in their collection."

These are just lovely.
