Wren House

I have several pieces of Harding Blacks pottery from the 60's because we had a beach house close to his and his mother's in Port Aransas. I did clay sculpture and we traded several pieces, who knows what has happened to those he had of mine. One piece that I have never seen anywhere else is a little wren house that hangs on the wall or a tree with a nail. It has a brown and beige glaze. I wondered if anyone had something similar to this?
