Authentic & original Meiji period c.1900, Japanese shunga erotic art woodblock print picture by Tomioka Eisen (1864-1905).  Measures approximately 14.8 cm x 20.8 cm.  Fantastic colors and impressions!  Great use of the deluxe printing technique referred to as urushi-e (black lacquer) to exemplify the hairlines, thus adding lustre to their beautiful and distinctive sheen.  Condition is great with minimal wear; very faint and slight diagonal crease going across the picture, but even under the 'right' lighting & most careful scrutinization, it's barely even noticeable.  No backing.  Please see and judge from photos.
 
 
A female voyeur beauty pleasures herself as she eavesdrops on another couple love-making in the adjoining room.  Truly an exemplary piece of shunga artwork by one of the Meiji Period greats - Tomioka Eisen!
