Breastplate and Backplate from a Set of "Four Mirrors"

Two round metal plates, breastplate and backplate from a set of four mirrors, by unknown artist. The plates are side-by-side, circular, and made of metal. They have a predominantly gold and silver color with a swirling pattern. The gold areas have a textured appearance and exhibit darker patches, while the silver areas are smooth. The metal appears weathered with dark spots scattered across the surface. The background is plain gray.
