Authentic & original Meiji period c.1900, Japanese erotic art shunga woodblock print picture by Tomioka Eisen (1864-1905).  Measures approximately 16.6 cm x 22.6 cm.  Very good colors and impressions.  There is also the use of urushi-e (black lacquer) to exemplify the hairlines, thus adding lustre to their beautiful and distinctive sheen.  Condition is decent with some wear, soiling, few stains.  No backing.  Please see and judge from photos.
 
A couple cooly & casually enjoy a smoke from a kiseru pipe while fornicating.  Truly an exemplary piece of shunga artwork by one of the Meiji Period greats - Tomioka Eisen!
