Randy was the first artist to perfect this thumbprint cane tech about 10 years ago, and though others tried to imitate him, he has always been THE BEST at capturing this super fun tech. I'm so glad he incorporated it into some marbles, but they are rare and hard to come by. This gem has NINE different colors of his thumbie cane! This is the first I've ever had to sell, so don't miss this sweet opportunity at a SERIOUSLY cool marble with a killer sparkly backside as well! Signed 'RW 13'.
