Authentic Edo period original, Bunsei era 8th year (1825), Japanese shunga erotic art woodblock print by Kunisada Utagawa (1786-1865).  From the classic shunga series, Hyakki Yakou.  Shunga picture measures 27.5 cm x 21 cm.  Very good colors and impressions.  Condition is very good with some wear and soiling.  No backing.  Please see and judge from photos. 
 
One of the rarest and creepiest shunga pieces ever made!  Here are a slew of genital creatures, ghosts, freaks, many inspired by Japan's own mythical creatures and stories.  My personal favorite is the penis hydra at the top left, which dips one of its many heads into a vagina-shaped pot full of vaginal fluid that oozes and drips from each pot.  Simply a great macabre piece of antique Japanese erotic artwork!
