I have an Art Pottery Wall Pocket of a Cockatto, it is made of a heavy clay and is glazed. It is white with pinkish areas on cheeks, and a black beak. It sticks out from the wall, like it’s looking at you. The artist Delphin Massier signed it. I have tried for endless hours to find out about it and the value of it. I know Delphin Massier is a famous french art potter, who had brothers who also where famous for there art pottery. Can anyone help me find what I’m looking for ????
