Bill Murray spent most of his marble-making career creating incredible cane style marbles, but he did have a few other styles in his arsenal, and the one he was most famous for, by far, was his face marbles. He did people faces, and monkey faces, and few others here and there (I have a rare dog face from him). He had a sweet process for making these, and the faces are SO pronounced that you will see them staring at your from clear across the room! They are AWESOME, one of my favorite marble styles of all time. I rarely let one of these go, but I am letting this two-sided monkey marble go, which has a monkey face on each side. The glass is flat/smooth, but the way he creates the shading gives it a true sculpted look to it, sort of an illusion. These are just so cool, and this one is VERY nice. Don't miss your chance to own a super rare marble like this!! Signed 'Murray 2002 13'.
