Authentic latter Taisho Period Japanese erotic art shunga woodblock print/lithograph picture toy set (shikake-e) c.1920s by an anonymous artist.  There are both a naked male and female with fully moving limbs.  Each figure measures approximately 17+ cm in height and nearly 3 cm in width.  Very good condition with just some light wear.  Details on both front and reverse of each figure.  Please refer to photos.  There isn't a slit cut into the female's vagina (as there are often is with toy/trick pictures), however, the male's erect penis does move up and down.
 
It's difficult to come by shunga shikake-e (toy/trick pictures), especially at this size.  Not to mention, an affordable price to procure a set of your own!
