An authentic Meiji period original, c.1870, Japanese erotic art shunga woodblock print picture book by an artist of the Utagawa School with numerous shunga scenes, inluding a group bathhouse scene with a lot of secret action happening underneath the water.  Also shown is an anal intercourse scene. 
 
Shunga book measures 18 cm x 12 cm closed.  Very good impressions.  Condition is decent+/good with some wear and soiling, bit of wormage on some pages, and no binding string, so the pages are loosely put together.  Please judge from the photos provided.
 
Approximately 28 picture pages within, while the remaining pages are kanji text pages.
