Circa August 1936-January 1937: Of the 20 vintage Fiestaware nesting bowl lids manfactured for the open market, the large #4 proves the most difficult to acquire, and the red #4 lid is the most desirable. Within six months of production, the Fiesta mixing bowl lid became the first item dropped from the line. In excellent condition, with no chips, cracks, touchups, or repairs and only the lightest of possible scratches, this rarely found #4 original red nesting bowl lid, measuring 7 11/16" in diameter, will brighten one's mood even when the sky seems dark.
