Slumber Party, a girl and Flinestone a boy
Flinestone is probably supposed to be Flintstone, but his card says Flinestone.
As an aside, see diptych I made about 4 ½ years later showing startling resemblance of two cats on a quilt (or fabric art, not sure). I'm posting it on July 11, 2016. I may put a link here if I get to it.
