I've created a wonderful Alice in Wonderland Art Pendant necklace with one of Tenniel's drawings. The drawing was changed a bit in Photoshop to move the characters inwards and create a more vertical piece for this picture. It was then colored in excruciating detail with colored pencils and watercolors, reduced and laminated for the final picture in 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, 1in.¬ x 1-11/16in. or 32mm x 40mm. It comes in antiqued silver-plate or antique gold-plate. I designed it to be a larger format, allowing the art to be seen better. It opens up and allows a new picture to be slid into the frame. The chain necklace measures 18 inches long and fastens with a lobster claw clasp.
