Circa 1937-1951. The 10 1/2" compartment plate was inspired from a suggestion by retailers Lazarus after pottery designer Frederick Rhead visited their stores in Columbus Ohio. The thick plate with deep wells and an abundance of bottom rings is a great version of the divided plate. This example in original green is in excellent condition with no damage to the dividers or elsewhere. Ink stamped on the back "GENUINE fiesta HCL USA". Measures 10 7/16" x 13/16" h
