This oval serving platter or tray by Wilton Armetale is in the older Acanthus pattern (there is a newer pattern with the same name but a different design). Armetale is a food-safe pewter alloy metal. The platter measures 13-1/2 by 10 inches. It's marked on the underside with the RWP in circle logo and The Wilton Co. There is some slight use wear at the center including typical very light, hair fine cleaning marks.
