If anyone has any idea how old and what brand this perfume bottle is please let me know. It has Czecho - slovakia embossed on the bottom. Found in the Saugatuck River at low tide, perfume is still in the bottle. I have found many bottles in this area from the 1930's.
Almost certainly 1930s on that one as well. That's about as art deco as a bottle can get, and vastly more in line with actual art deco design than most "art deco" sodas are. No idea about what perfume it contained though, you'd need to find a labeled one to answer that.
