Circa 1949 - 1959. 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 50s forest green is in excellent condition with no damage to the dividers or elsewhere (please note one small glaze skip on the front divider, shown in the 3rd photo at about 4o'clock, and one glaze skip on the back of the plate). Ink stamped on the back "GENUINE fiesta HCL USA". Measures 10 7/16" x 13/16" h
