Tiffany produced several models of solid-bronze paperweight animals of dogs, lions, owls, etc. This example is a bulldog, I think. (Someone please help me out with the breed of the dog). The finish is patina, with even wear. The paperweight is properly signed underneath TIFFANY STUDIOS NEW YORK and numbered 888, as well as an enameled collector's number D1670. It measures 2" tall.
