Well not a FacePot but it's a face! This tile is one of a series. The original pieces I pressed and applied to the side of my house. This features my signature fabulous "luster" glaze.
They're pretty ubiquitous elements of the facade of Luna Parc.
These measure about 7"/18 cm square. Note there is a slot in the back of each tile for hanging on the wall. These can also be mounted permanently with thinset mortar but also note these are NOT suitable for outdoors in cold climates.
