Authentic Edo period original, c.1827, Japanese erotic art shunga woodblock print picture by Kunisada Utagawa (1786-1864).  From his shunga series, Sento Shinwa (New Stories of the Bathhouse).  
Shunga picture measures approximately 20 cm x 26.5 cm. 
Very good colors and impressions.  Condition is good with some wear and soiling, cropping.  In particular, this is originally a trick-picture fold-out scene, so clearly the extra fold-out shunga images are missing, which does tend to happen with books and prints from the early 1800s as they tend to go missing over the centuries.  Please see and judge from photos provided.
 
Still an excellent original Japanese bathhouse shunga woodblock print picture of a group of Japanese women enjoying a traditional bath together.
