Vintage Christmas Ornaments Balls Pair Silver Blue Mid Century 2

Nice pair of hand-blown, hand-painted Christmas ornaments. Silver matte balls with blue painted design. I'm guessing these are mid-century, 1950s - 1960s, Poland or another Eastern European country. Great vintage condition. Significant 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"DIA.
