I have seen this particular piece attributed to Archimede Seguso after looking at a lot of the work of that company I am going to concur it fits in with their style. This is a mid-century modern piece maybe from the 50's 60's I see other people calling it a salt, I guess it could be, I used it as a toothpick holder. Size is 2.25 inches high, 3.4 inches long. Condition is excellent.
I have been collecting Art Glass for about 20 years. I used to live next to a large flea market and a couple big antique malls. So I would pick things up whenever I saw something that fit the collection or I thought was a good deal. I sold about 50 paperweights last summer and I am getting pushed to sell the rest as I am relocating. Please check out my ebay store as I will be putting things up all summer. Thanks
