Authentic Edo period original, c.1827, Japanese shunga erotic art woodblock print by Kunisada Utagawa (1786-1865).  From his highly coveted shunga series, Shunka shuto shiki no nagame (Spring, Summer, Autumn and Winter: Prospects for the Four Seasons).  Shunga picture measures 34 cm x 25.5 cm.  Great colors and impressions!  Also nice use of urushi-e (black lacquer).  Condition is very good with some wear & soiling, two wormage spots at top border.  No backing.  Please see and judge from photos. 
 
About this classic shunga series:  "Today one of Kunisada's most valued works, Shunka shuto shiki no nagame is exquisitely printed and would have been an expensive book to produce.  This indicates that it may have been a commission by a wealthy townsmen.  The appeal of this album lies in the clarity of the imagery, which is not cluttered by surrounding blocks of texts."
