Arthur Hash. I loaded up on his stuff (the large white ring in the bottom pic and the guy-in-a-suit-with-a-mohawk) at the Velvet Da Vinci Gallery in San Fran
Recently I got the below ring off of Arthur's Etsy site. It's a little too clunky for even my liking, so I might make it into an amazing necklace.
I really love his work. You have to check out his site. I love the suttle humor in it all. He graciously included this too, which was really sweet:
Oh yeah, and I'll be in Sin City in 24 hours. Hell yeah!
