This awesome piece is one of Chris' amazing sphere ground marbles that features his Tom Petty murrine. Chris took a piece of the Petty cane and rounded it out in the sphere machine, giving us really killer lines and features in the marble. These are my absolute favorite marbles from Chris! The images on the reverse sides end up being mirror images which is cool. Chris did a lot of famous people images of course, and I think his Tom Petty image is one of the best and cleanest he ever did, truly amazing artistry and glass work! Suuuuper rare chance at this one as I've never seen another Petty marble for sale, don't miss it!
