This dude is amazing! I've been looking at some of his art for the past hour or so, and have to say he might just be in my top 3 artists now with Guy and BranJo. The Dog Fish Head collection is awesome, I wish I wouldve known about them when they were for sale! The MMJ poster is obviously awesome.
There doesn't seem to be a contact link on his website though, or I'm going crazy...
Marq is solid people, and actually a fairly good friend of mine. They used to live real close to us and we hung out quite a bit, but he now lives in Pacifica. He's done 2 MMJ posters, the Filmore NYE 06 and the 08 LA greek poster, the latter was commissioned by the promoter and not sold at the show. I have quite an extensive collection of his work.
there's a contact tab on the bottom of his homepage.
