Daisy and Joy Are Crazy Ses You! Hand-drawn Postcard

One last card for now, and this one I think in a league entirely of its own, really one of my favorite things I've found. I love the Riot Grrrl attitude of this, though I believe it was done several decades prior, and really want to know all about Joy and Daisy and who sed they were crazy!  The outlined lettering, the faces, the outfits, the hairstyles, the jumprope and the pommel horse--to my sensibility it doesn't get much better than this:)

5 1/2" x 3 7/16", pencil, and in good condition.
