Circa 1937-1959: The Vintage Fiesta egg cup would have been slip cast with the outside rings jiggered by hand. More hand work would involve shaping the foot on what is most like a woodworkers lather, rings would have then been jiggered around the base by hand as well- thus resulting in a wide variety of shapes and ring patterns in the Fiesta egg cups foot. Some will flare out much more than others or become thinner from extra shaping, most will be marked in the mold, although occasionally they will show up unmarked. Larger than most egg cups. The Fiesta version stands 3 1/8" tall and 3 3/8" wide.
