Size is 3.25 inches across. 2 inches tall. This is unmarked. I am claiming it as a Murano based on the ground base which is very flat polished smooth. It also has this latticino in it and that is a very Italian thing. It is not what I typically see as Murano though. I think it may be older then a lot of the paperweights I have had in my collection. I do not know the age but I am going to guess it is 1960's or earlier. The condition on this is fair which will be reflected in the price. The top is pretty good but it has an impact mark on the side. A mark and a fingernail crescent crack. These are under the glass, in other words when you run your finger across this area you can not feel any difference. I have circled that in one of the photos.
