Hello, I have a total of 49, 4x4 inch tiles. I got them in Santa Monica California. They are all plain with no details of figures or embellishments. A few are bull nosed. There is a mixture of matte and glossy. The backside is sandy in color. I am attaching the photo of the total range. They do not have any names written or etched on them. I don't know who produced but am assuming they are from California. I have more images if needed.
That is my question. Does anyone know the origin of these tiles? Any information is appreciated. Thank you, Terry
