Authentic Edo period original, c.1839, Japanese erotic art shunga woodblock print pictures by Keisai EISEN (1790-1848).  From the shunga series, Ana no ukihashi.  There are 7 pictures from this series, with the largest diptychs measuring 22 cm x  18 cm each.  There is also a smaller surimono shunga booklet by a member of the Utagawa School c.1840s.  It has 9 total shunga pictures.
 
Good colors and impressions.  Condition is fair to worn with some wear, soiling, foxing.  No backing on the 7 Eisen shunga pieces.  The shunga pictures in the booklet are attached to each page.  Please see and judge from photos.
 
This is an economy lot of rougher-conditioned shunga, hence the affordable price.
