An imported Italian marble chunk I hand picked in a basement warehouse for sculptors in NYC. It was pricey, but what isn't in that city. I remember paying $15, once, for one cocktail in a hotel bar across the street from a Maddison Square Garden Dead Show in the early 90's, that was unpresedented then. But I've never seen a bust in marble of someone with natty dreadlocks especially one from Kingston who smokes herbs! So... I made one!and not in any traditional proportions either. It's art! and it's from New York City,... kinda! But Bob deserves it, a true musical genius!
