Would need to research the tiffany line.
Pottery in Ruba Rombic? Yes! The designer of the Ruba Rombic line, Ruben Haley designed a line of pottery in the style of Ruba Rombic for the Muncie Pottery Company in Muncie Indiana in 1929. The Muncie glazes along with the pottery medium bring out even another dimension to the cubistic forms and shapes.
