This is a beautiful vintage Czech glass perfume bottle from the Art Deco era of the 1930s. It has a large cut and frosted stopper with a design of flowers. The bottle is larger than average, and square. It has a ground and polished pontil and it is acid marked Made in Czechoslovakia. I tried to photograph the mark, but it doesn't show very well.
The bottle itself is about 3 inches square and about 1 1/2 inches tall. The stopper is about 4 inches by 4 inches. The dauber is broken off of the stopper, as is often the case. There is some cloudiness visible in the bottom of the bottle. Aside from these issues, and normal shelf wear, it is in good condition.
