Old Vase

This vase is very old hand blown glass. It is hand painted and is very unusual. I have been searching for years and can not find anything like it or any style of glass that matches it. I'm thinking it may be Greek or Italian. It is about 24" tall and 5" across. Our family acquired it with a bunch of other items from WWI, WWII and Early American antiques. This item has no mark or any other identifiers to help locate/determine it origins. Anyone that can give any clue on it please chime in.

This item will be for sale when I can find out what it is worth. My mother was offered $2000 back in the late 70s by a dealer that could/would not tell her the value or any thing about it.

Thank You
