New Holland is one of the few promotional patterns released as a set. The two-piece Oval Casserole set debuted in 1973 with the 1 ½ quart casserole (043) and the 2 ½ quart casserole (045). The set included a reversible cork trivet that could be flipped to the correct side depending on the casserole size in use.

The New Holland casseroles are both solid blue with a white opalware lid designed with blue and red Pennsylvania Dutch-inspired floral folk art.

Corning Glass Works offered its first patterned opalware gift set in 1953 when the Heinz Baking Dish was sold in grocery stores. Widespread distribution of promotional patterns occurred after the overwhelming success of the 1956 release of seasonal “decorator casseroles.” Using existing Pyrex shapes, gift sets featured new patterns offered for a limited production time. They often came with mounters, cradles, or candlewarmers and were advertised in the spring to appeal to Mother’s Day and summer wedding shoppers and in the fall to give the holiday gift-buyers something new. Corning continued to produce gift sets through 1983, creating nearly 135 different gift set patterns during that time. Corning intended these pieces to be sold for a limited time, and directed retailers to remove older, unsold promotions from the shelves.

Often, patterns used for these gift items were unnamed, or given names descriptive of the dish’s purpose, like “chip and dip set.” Collectors over the years have assigned names more reflective of the specific pattern.
