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 cm x 9.6 cm (koban size).  Great colors and impressions!  Condition is very good with some light wear; barely visible partial hanko stamps showing near top left and right edges.  No backing, aside from bit remnants of album backing on the corners only.  Please see and judge from photos.  In short, a stunning Kuniyoshi shunga piece!
 
Great Japanese erotic art scene of a vulva-faced courtesan ghost accosting a horrified man before his nightly slumber.   Another shunga gem by my personal favorite, Kuniyoshi!
