Authentic Edo period original, c.1830, Japanese shunga erotic art woodblock print picture by Kuniyoshi Utagawa (1797-1861).  From the haunted & sexually macabre demon/ghost shunga series, Kaidan hyakki yagyo (Ghost Stories: Night Procession of the Hundred Demons).  Shunga picture measures approximately 13.2 cm x 9.5 cm (koban size).  Very good colors and impressions.  Condition is decent+ with some wear and soiling, crease line down the middle of the picture.  No backing, aside from a few remnants of album backing.  Please see and judge from photos. 
 
Great Japanese rare & dark shunga scene of a creepy-actor-ghost character inserting his fingers into his vulva-like mouth, essentially orally masturbating.  Another classic shunga scene from this great macabre series by my own personal favorite, Kuniyoshi Utagawa.
