I believe this beauty dates from the 1920s or maybe 30s, and am sorry not be able to properly capture the lenticular effect! Though certainly meant to be risqué, it is quite modest by today's standards; she essentially shimmies a bit in a seductive sort of come hither!  Sold as found with old masking tape around the borders and on the back, which I really love as they make it seem as if it was handled so often the edges needed protection! 

6 7/8" t x 4 1/4" w.  There is a horizontal scratch across the middle and a bit of additional surface scratching as documented, in my option just adding to its great aura!
