This is but one plate in the Iroquois Casual Brown line by Russel Wright. It measures 10 inches in diameter.
My only issue is one knife cut on the coup rim, not on the edge. I think it not objectionable especially if to be used, but it takes away the investment designation the plate otherwise would have.
Orphaned treasures have several items in the casual brown (or nutmeg) color and also in the blue.
