Authentic Meiji period original, c.1910, Japanese erotic art shunga picture by an anonymous artist, although clearly after Kunisada's famous shunga parody series, Koi no yatsufuji from 1837.  More specifically, it's a smaller shunga version of the famous scene shown here in the 4th image, that of the canine hero, Yatsufusa, having sex with his eventual bride, Fusehine.  Moreover, as the story goes, she eventually gives birth to eight pups, as well. 
 
The technique used here to produce this picture is copperplate printing, which gained popularity through Western influences in the Meiji & Taisho Periods.
 
Shunga picture measures 8.4 cm x 6 cm.  Very good colors and impressions, as well as some gold mica (metallic pigments).  Decent+/good condition with some wear & soiling, creasing.  No backing.  Please see and judge from photos.
 
A rare and unusual shunga paying homage to one of the Edo period’s most infamous shunga parodies, bridging the transition between traditional woodblock print erotica and Western-influenced Meiji production methods.
