Super Satisfying Superior Bone Rings on Sky Blue CardA perfect exemplification of the fact that inexpensive little things can deliver as much pleasure and aesthetic satisfaction as "significant" ones. I'd hang this next to a Sol Lewitt or Agnes Martin or Donald Judd if I had one handy, ha. Like a grid of life buoys, too. Or clouds in the sky. SUPERIOR. 4 3 8" x 2 3 4" 1940s. Some wear around the edges of the card, all to the good I think.
