This is another of Mark's famous animal skins, gorgeous black and white detail in this one, an absolute wonder in the world of marbles, and a superior example. This is a GREAT price for this marble. Every collection needs an incredible animal skin in it, and this is a sweet one to have! Like all of Mark's skins, this one mimics a Grevy's Zebra pelt which he photographed at the Smithsonian on a data gathering trip some years back, and it is true to form in all of its detail. Astounding stuff in glass!! Made in the year 2000, a classic.
