This one here is for you marble historians out there who like to collect serious marble history! This sweet piece was made by Lundberg back in the late 90's after he was talked into making some marbles. You see, the Lundbergs are VERY famous paperweight artists, and thus have only made a very small number of marbles in their time, and most of those have been their Earth style pieces. I think it was most likely Bert Cohen who got Steven to make these butterfly marbles, along with a few others, and they are really beautiful slices of contemporary art glass marble history! I have 3 others in my collection, and those are the only ones I've ever seen besides this one. A rare opportunity to get some wonderful history into your collection, don't miss it! Signed 'SL 99'.
