Authentic Edo period, 1830 Japanese erotic art shunga woodblock print picture by Kunisada Utagawa (1786 - 1865).  From his series, Fuzoku sangokushi.  Shunga picture measures approximately 22.5 cm x 28.3 cm.  Very good colors and impressions.  Condition is fair/worn due to some wormage, black ink stains, soiling, and general wear.  Please see and judge from photos provided.
 
An odd and darker shunga scene of a woman who has been violated, still tied up and floating out at sea.  Some men appear in a boat, but judging by the one's erection, it doesn't appear they will be freeing her either.
