We have never seen even one of these before. The Leaf Dish was one of four small pieces shown in the 1961 catalog and it was advertised as being available in Mahogany Brown glaze only. (We have seen the square dish rarely, only in brown.) In spite of that, there must have been some demand for the Leaf Dish in Seagull Blue because here is set of four in unused condition, made contemporaneously with matching clay body and signatures. Deep and lustrous blue glaze with glossy surface. Each measures 5.5” x 3.5” x 1” deep. Sold as the set of four only.
