This is an assemblage mounted on a 7 inch rusted and aged metal cog. I uses plaster molded doll and a little bird and a chippy painted frame the main focal piece. A jewelry piece hangs from the bottom of the frame. I backed the doll piece with a cool holey round piece of metal. I backed that with a page from a vintage physics book so that the numbers show through I used more text from the book around the metal piece.
