These eight scalloped square glass plates are in the 1930s Marshfield cut decoration by Rock Sharpe. They're about 7-1/2 inches across, 8-3/4 inches on the diagonal. The arched ovals and floral cutting was done by Cataract Sharpe Mfg. I think the blank plate was made by Libbey, though Bryce Brothers, Heisey, and possibly others supplied glass blanks to the Cataract Sharpe as well.
The plates are in wonderful condition, crystal clear with no chips, flakes, or fleabites. There are a very few insignificant tiny marks to a couple of the plates which may be from stacking, nothing that looks even close to a utensil or knife scratch. I have matching Marshfield oyster or fruit cocktail stems listed elsewhere in my shop.
