can anyone tell me where I might find out the origin of a set of pressed metal wall plaques or what they might be worth. One has a seated, bronze bearded king w/crown holding a staff w/servant knealed holding a bowl with maybe bread in it. The other is of a seated long haired lady wearing a small pointed hat with 2 feathers playing a harp with a vase & cup in front on ground. Both plaques are round w/scalloped down edge.Both have a ring of leaves & berries or flowers. The figures are gold toned w/bronze colored hair and have a black background.
