Green Glass Decanter with two pinched sides and very fine delicate glass, top was designed as a small shot glass that fits perfectly on top to seal spirits.
I have been unable to determine maker and it maybe art glass or possibly made by Blenko Glass in the 1950's. The decanter has two Sides that are pinched.

Here's more information about this type of item:
Material and Appearance: This decanter is made of green glass, a color popular in decanters from various eras, including the 18th century and mid-20th century. The green hue can be achieved through various methods, including the natural presence of iron oxide in the glass or the addition of elements like uranium in older pieces, which can give a fluorescent effect.
Purpose: Decanters are primarily used for serving wine or spirits, allowing them to breathe and enhancing their aroma and flavor. They can also be used for other liquids like water, essential oils, or even as decorative pieces. I was told by a glass dealer that it looks like designs by Joel Philip Myers, who is known for his distinctive hand-blown glass pieces, including decanters, from the mid-20th century.
