This is a beautiful vintage French opaline glass perfume bottle in a lovely shade of green. It was made by Portieux Vallerysthal in the early part of the 20th century, probably in the 1920s or 30s. The design is called Suedois (Swedish). It is somewhat unusual to see it this design in green,
The bottle itself measures about 4 inches and to the top of the stopper it is about 5 inches. It is in very nice condition with no cracks or damage to the glass. There is one small fleabite chips to the bottom of the stopper (very common in perfume bottles) and there is a small area of roughness on one side of the stopper.
I also have a larger version of this bottle, listed separately. The last picture is both bottles together. This listing is for the smaller bottle only.
