Here is a wonderful set of six "Genuine Glasbake" custard cups. The cups are unused in their original box with the original packing paper. The cups each hold 4 ounces. Each custard cup is marked Glasbake USA 286, which is also listed on the box. These custards were produced prior to 1961. The custards are shown in "Florences' Ovenware from the 1920's to the Present" by Gene & Cathy Florence.
