Vintage Christmas Ornaments Ball Set of 3 Purple Hand Blown Glass

Nice set of 3 purple mercury glass Christmas ornament balls! I'm guessing these are mid-century, 1950s - 1960s. Great vintage condition. Some wear to the paint, as expected for something this age, plus tarnished spots. No chips or cracks, though I did not remove the caps to check underneath, where chips/cracks are very common. Approximate dimensions: 2.25"DIA
