I assume it has no markings on the bottom. It does have sort of a Art Deco look, but my guess would be a bit later. From the pics I would guess it to be a barrel Shaped vase, the lip looks like it was not made for a lid. Most likely had a paper label that has been taken or washed off, which is more why I lean for a later date like 40's or 50's. It is for sure worth the price, it has a wonderful unique look and subtle green color.
