Two of our panels did appear in an exhibit that took place May 12-June 30, 1959 at Corning Glass (not the Museum), 717 Fifth Ave., New York, NY. The exhibit was entitled the First American Exhibit of "Gemmaux de France" and featured work by Cocteau, Picasso, and other "Famous Artists and Young Talented Artists." I love that subtitle to the exhibit!
The two pieces we have as appearing in this exhibit are: Mere et Enfant and Torse Rose. Unfortunately, these pieces have never been photographed, since they came to us in 1993, when we weren't routinely photographing new accessions. They were donated to the Museum.
They are not on display and difficult to access, but our curatorial department was able to find these snapshots taken of the pieces. I'm afraid that is all, image-wise, I can offer.
