Street Art

I was given this by a street artist a few years ago in a bar in NY where the guy was frantically painting on the sidewalk of the bar and occassionally dipping the bar for some warmth and drinks. I was drunk and can't even remember what bar it was. i think it was manitobas. I also have a few wooden panels the guy painted. anyone know who did this? I think its awesmome. Its painted on some found curtains or table cloth.
