This incredible image from Zach is an amazingly accurate representation of the famous 'Ancient of Days' watercolor etching by William Blake. Look it up on Wikipedia and you'll be astounded! But heck, this marble is worth it alone just for those awesome star cluster millies that go around the outside of the image, SO cool. This was an instant classic as soon as Zach released it back in 2009, and is a must for every serious Jorgenson collection!! I have not seen many of these available out there and it is fairly rare. Oh, and I almost forgot to mention that backside - killer color!
