Metal Picture Frame Gardeners Garden Boots Watering Can Pewter ?

The frame itself measures approx 4-3/4" tall at highest point and 6" across at widest point. The actual photo portion is 3-1/2" tall x 5" wide. Not sure if this is actual pewter but it is very heavy. A few marks on the metal portion (see pics). The back is a black velvet type material which shows a few marks / wear from use. Smoke free.
