Bohemian Cocktail Shaker and Glasses

This is a Bohemian cocktail shaker and 4 glasses. The shaker has a black painted stopper and foot, and is a strange shape with a flying saucer stopper. The glasses have black painted feet, 3 dimples and averted lips. Underneath the shaker has Made in Czecho-Slovakia stamped in white in a circle. It might be art deco or it might be 50s.

This is not my usual thing, but it was so crazy I had to have it. Any help with identifying it in more detail would be gratefully accepted.
