1976 Advertisement - Corelle in Four Patterns

This particular page can be dated to 1976.  The patterns featured are Spring Blossom Green, Butterfly Gold, Old Town Blue and Winter Frost White.

The ad emphasizes the flexibility of the different sets available.  Complete sets could be purchased as well as additional pieces in open stock.  At the time, open stock meant packs of four for items like bowls and plates, but serving bowls, platters and cream & sugar sets were sold singly.
