Purchased 20 years ago in Los Angeles, USA. I don't smoke, so I kept it as interior decoration. It's a mid-century modern ceramic product made by California Originals. The manufacturer is California Originals Pottery. It is stamped with "U.S.A." and "531". This is a vintage ceramic product characterized by its mid-century modern style. It features orange, yellow, and brown drip glaze and can be used as an ashtray or a small item holder. Size: Length: 230mm Width: 345mm Height: 50mm *Measurements are approximate.
