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 some deluxe printing techniques: There is the use of urushi-e (black lacquer) to exemplify the hairlines, thus adding lustre to their beautiful and distinctive sheen.  Gofun (a pigment derived from the burning and grinding up of seashells) is also used here to highlight the act of penetration & the couple's genitalia.  Condition is great with minimal wear, if any.  No backing.  Please see and judge from photos.
 
 
A male lover intimately hugs the breasts of his female partner as she methodically inserts his penis into herself.  Truly an exemplary piece of shunga artwork by one of the Meiji Period greats - Tomioka Eisen!
