This Mid Century copper kitchen food mold has a shamrock or 4-leaf clover embossed on the front. It's 7-1/4" diameter by just under 2 inches deep. The mold looks like it was used only for wall display - the interior lining is shiny and scratch-free. Some light marks and tiny scuffs on the front from normal cleaning and storage, otherwise excellent condition. I didn't find any markings but the mold has a heavier weight than modern gelatin molds.
