Each piece signed Yamada (the city) Japan and Nipon (Nippon is usually spelled Nippon. A little History (Porcelain with a face of an oriental woman seemingly impressed in the bottom of what appears to be only their cups. The picture impressed in the porcelain is a "Lithophanes". This type of design was made in Japan between the late 1930's and into the late 1950's/early 1960's, mostly for export.) That info controdicts the time line with exports(A general rule of thumb to follow for marked pieces of geisha girl porcelain is as follows: vessels marked “Nippon” dated between 1891 and 1921 and items marked “Japan” or “Made in Japan” post-date 1921 (Litts 1988:58). Vessels marked “Made in Occupied Japan” I do have other Asian items listed if interested :) Thank You For Visiting :) ** I Ship Out Same Day** *All questions encouraged and additional photographs will be sent upon request!
