Old Town Blue is relatively unique in that it was released first as a Compatible Tabletop set for the Corelle Livingware line. Only one baking dish (473) was ever released, though not advertised in the Pyrex catalogs.
The Corelle Livingware collection contains napkin rings, a butter dish, a round margarine dish, a gravy server, teacups, a footed custard bowl, mugs, a cream and sugar, and salt and pepper shakers.
While there were no opal Pyrex patterns of this nature other than the one baking dish, when it was released it was advertised as the perfect complement to the Homestead pattern. Old Town Blue was called “A breath of nostalgia in an air of fresh design…Dainty swirls of fanciful flowers of deep indigo blue say Old Town Blue is something nice.”
When Corelle was introduced in England and France one of the patterns released was Old Town Blue. The design was officially discontinued in 1982.
