Authentic Meiji period original, c.1899, Japanese erotic art shunga woodblock print crepe picture by Terazaki Kogyo (1866-1919).  From his famous series, Izumo no chigiri (Pledge of Izumo). 
 
Shunga picture measures 25.5 cm x 19 cm.  Very good colors and impressions.  Condition is good with a few vertical crease lines and some mild spotting in the middle of the picture, softly worn bottom corners.  Album backing.  Please see and judge from photos. 
 
This is considered the Meiji Period iconic shunga piece, much like Hokusai's Octopus-themed shunga artwork, Dream of a Fisherman's Wife is to the Edo Period shunga genre.
