A 2 1/2 and 1 1/2 quart set of glass Pyrex mixing bowls in the Early American" pattern featuring transferred images of early American colonial kitchen items. The bowls are both marked on the undersides and are in very good condition, with little to no indication of prior use and clean crisp graphics.
From Wikipedia: Pyrex was created in 1915 when chemists at Corning Glass Works invented a new kind of borosilicate glass that could withstand extreme temperature fluctuations. Soon after, popular over-to-table-to-refrigerator household kitchenware was introduced. The continued popularity of Pyrex over the years saw the creation of nested and Cinderella mixing bowls, casseroles, divided servers, refrigerator sets, carafes, and dinnerware (to name a few) in bright colors and lively patterns.
