"[The ads] in the 1930s [had] appeals to the everyday consumer concerned with low prices and practicality. Corning began early on to promote Pyrex as the perfect gift for Christmas, Mother’s Day, and for weddings. Brides, mothers, Santas, and newlyweds appear regularly in Pyrex ads, particularly in the 1940s and 1950s."
