Two versions of the poster from last nights Pearl Jam show were created by Ames Bros. The one shown on top was sold at the Ames booth for $40 and signed and numbered out of 500. The other one was at the Outside Lands Festival merch booths.
I like the colors on the first one but you can't read Pearl Jam anywhere. EMEK's Neil Young poster that spelled out his name was a much better execution of this concept.
