Alonzo is one of six American Wildlife series of cabinet knobs.  He measures 1-3/4" (h) x 1" (w) x 1-3/4" (d), and is cast in non-leaded pewter. He comes with a 3-32 x 1" screw for mounting in a door or drawer.
Alonzo is the husband of Nancy Bear and the papa of Junior Bear.  They all look great together, but would be fine among other animals of the pewter variety.
