Retro 70s wall art sculpture, copper and brass hummingbird plaques set

70s vintage hand wrought metal wall art pieces, a set of three wall plaques with hummingbirds and flowers, 3-D style, made to stand out from the wall.

Each decoration is a little different (one with a single flower, one with two flowers, one with three flowers), sizes range from about 6 1/2" to 8" long. These are not signed these we could see... possibly Homco?
