Authentic Edo period original, c.1842, Japanese erotic art shunga woodblock print picture by Kunisada Utagawa (1786-1865).  From the shunga series, Shiki no sugatami  (Viewing Forms in the Four Seasons).  Shunga picture measures 22.5 cm x 27.6 cm.  Very good colors and impressions. Condition is good with some wear and soiling, mainly at top right corner and bottom right corner.  Please see and judge from photos.
 
Another excellent scene from this series as a servant carries a nice meal to be delivered upstairs, while a couple seemingly cannot contain themselves as they openly fornicate on the balcony in plain view.
