VTG Rare Irvinware Copper Series

Must be very rare..I can find no other. No breaks or chips. Been stored in original box in attic for years. From 1950"s/1960's I saw them use it once. I took out for pics Irvinware Copper "Gourmet Susan" 3 Relish Glass Inserts. Clean. However patina on copper has not been touched. Box had been stored in home with years of smoking.
