Authentic Edo period original, c.1840, Japanese erotic art shunga woodblock print picture by Kuniyoshi Utagawa (1797-1861).  From his shunga series, Keichu ogarakuri.  Shunga picture measures approximately 22.3 cm x 27.5 cm.  Very good colors and impressions, as well as gauffrage.  Condition is good with some wear and soiling, most notably at bottom corners.  No backing.  Please see and judge from photos provided.
 
A fantastic Japanese original shunga woodblock print picture depicting a fireworks festival with the bridge overly thronged with onlookers and partygoers.  The couple on the pleasure boat at the forefront don't seem to be enjoying themselves as numerous drunk ruffians bother them.  Good to see not much has changed over the years (sarcasm).
