This is a French art glass scent perfume bottle, or for cologne, and most likely produced near the Patin region of glassmakers. The date is circa 1910.
The bottle is 5" to the top of the stopper and 3" wide at the belly.
The interior glass and the stopper is clear. The exterior glass is some type of paste-glass, with four finely detailed intaglio cut autumn leaves and some additional coloring within the glass; each side of the bottle has a different leaf. The leaves are cut into the glass, not raised like cameo, and the definition of the cuts can be seen with the eyes and felt with the fingers.
The stopper has a round top with a bulb on top that is covered in gold. There is another gold band towards the bottom. The stopper is original to the bottle.
The rim of the bottle is flat with a lip. There are a few air bubbles within the neck and rim and the outside edge has a few indentations in the glass. The bottom of the bottle is flat with no pontil. The upper edge of the paste glass, where it meets the clear glass, has an orange color, and some of this orange color is also on the stopper. The paste glass is rough to the feel with the fingers as there are additional cuts on the glass that are not part of the leaves. The bottom shows age wear.
There are no nicks, chips or cracks.
