Molded glass perfume bottle by Coty. An old one, and the scent was Chypre de Coty. It looks to be a celluloid screw on stopper or top. Lovely design, but I'm not sure if it a design by R. Lalique who use to design bottles for Coty in the early days. This first came on the market in 1913 which is Coty's early days. It is a very difficult bottle to find, of the classic small Coty mini's. No chips or cracks. The design is typical of a Lalique design, and is on both sides of the bottle. Molded glass, Coty is on the bottom of the 2 1/8 inch bottle.
One that was boxed, on a popular auction site went, for over $150.00.
