Authentic Edo period original, c.1855, Japanese erotic art surimono (privately commissioned, high-quality print) shunga woodblock print picture by Utagawa Kunisada II (1823–1880).  From his shunga series, Shunkyo karami-dako (Spring Games: Grappling Octopus)  
 
Shunga picture measures 9.2 cm x 12.2 cm.  Very good colors and impressions.  Very good condition with some light wear.  Thin backing with embossing/impressions still clearly visible.  Please see and judge from photos.
 
An oddly comical original surimono shunga woodblock print picture of a couple playing, what could be, a very dangerous game of kyudo (Japanese archery).  The woman is using her feet to shoot the bow, while the male seems quite content in using his giant erect phallus as the target's post.  Good luck, friend!
