I've created a wonderful Alice in Wonderland Art Pendant necklace with rubber stamps.  I stamped Tenniel's drawing of Alice with the Queen of Hearts.  I colored the piece in excruciating detail with pencils. Afterward, I scanned, reduced and laminated the final picture for this pendant.
The necklace and frame is of my design (with an ivy pattern on the edges) and was manufactured for me. It measures from the outside edges, 1 inch x 1 11/16 inches or 32mm x 40mm.  It comes in antiqued silver-plate or antiqued gold-plate.  I designed it to be a larger format allowing the art to be seen better.  It opens up, allowing a new picture to be slid into the frame.  The chain necklace measures 18 inches long.
