This is a beautiful antique Heinrich Hoffmann Art Deco etched crystal perfume bottle made in Czechoslovakia circa 1930's. It is a translucent black color and features a frosted intaglio of an Aztec man with a bird, probably a Quetzal, and a cut crystal stopper in the form of Quetzal.The Hoffmann mark of a butterfly can be found on the face of the bottle. It measures about 6" tall with stopper and 4.75 " wide at widest part of bottle, and the stopper is about 5 wide. It is in very nice condition, scratches on bottom of bottle, a very small chip at the tip of the bird's crest (see last photo). The stopper is stuck in the bottle and I don't dare to try to pull it out in fear of it breaking the bottle or the stopper or both.
