Vintage Mid Century California Pottery Ashtray

Very cool vintage mid century ceramic ashtray from California Pottery Co. It is marked 576 underneath and is glazed with a variety of color including red, green, black, brown and yellow. It measures 9.75” x 7.5” and does have one small chip underneath on a corner. Fortunately you can’t really see it unless you turn it upside down. I zoomed in so it looks larger than it really is.
