Size is 2.75 inches across. 2.25 inches tall. I do not know how old this is. I have had it at least 10 years. Condition is excellent. I saw a tiny dot near the top and pulled out the magnifying glass. Appears to just be a micro air bubble under the glass. If you flip it over there is a large bubble on the bottom. You see it in the picture I took. It is just under the glass you can't feel it and it is on the outside of the ribbons so you don't see it from the top. Basically shows as new.
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
