This is a French Émile Gallé cameo art glass scent perfume bottle, or cologne. The bottle is signed on the side in raised cameo. The date is circa 1906 to 1914.
The perfume bottle is not a reproduction; it is authentic and direct from an estate, and was with the same estate for over 50 years. The cameo perfume bottles have not been reproduced, nor have the miniature cameo pieces. You can view the same glass and cameo leaf pattern in the book "French Cameo Glass" by Berniece and Henry Blount, page 64, Figure 82(C), in the form of an 8" vase.
The base glass has several layers and is a mottled dark yellow. The top layer of leaves and stems is brown. The detail on the leaves is excellent. The top of the bottle has a metal cap, brass most likely and the atomizer screws into the top. The atomizer is a black fabric. When the top is pulled out, there is a long clear glass rod, which shows staining from using perfume in the bottle over the years. The bottom of the bottle is polished flat, with some of the brown glass over the bottom.
The bottle is 7 3/8" high to the top of the metal and 2 ¼" wide at the body.
There are age scratches on the bottom. There are no chips, nicks or cracks. The metal has age patina and wear. I don't know how to use an atomizer bag to test this one, but it appears intact.
