Czechoslovakian iridescent cut crystal perfume bottle

This is a truly wonderful perfume bottle from Czechoslovakia. It has a rainbow irridescent inside and is cut to resemble ice cubes. It has a cut crystal drop stopper. This piece is from the 1920's. It measures 1 3/4 in. wide and 6 1/4 in. tall. It is in excellent condition, although it still has remnants of the original perfume in it. It does smell lovely. Enjoy!
