Authentic Edo period original, from the Kaei period (1848 - 1853), Japanese erotic art shunga woodblock print picture by Kunisada Utagawa (1786-1865).  From the shunga series, Shunshoku Tamazoroi (An Assortment of Pleasure in Spring).  Shunga picture measures 24.5 cm x 28.9 cm.  Very good colors and impressions.  Also some deluxe printing techniques such as mica (metallic pigments), as well as gauffrage used on the fox to highlight its fur.  Condition is fair+/decent with some wear, soiling, wormage, thin washi (Japanesse rice paper) backing.  Please see and judge from photos.
 
This is the second scene of three parts from the shunga series, Shunshoku Tamazoroi.  Now the male (actually a ghost) is joined by a fox spirit who together ravish the unsuspecting Japanese beauty.
