I can't say enough nice things about Portland-based graphic designer and poster maker Dan Stiles. He really came through for me when the post office mangled a Ween poster I bought for Dan for his bday last month (here).
I also can't say enough nice things about his work, which is think is super pretty and worthy of your dollar bills. His latest include Cat Power, Kasabian, Frank Black, and Ray Lamontagne. (Note: His studio will be closed and vacant for the holidays, any orders received after Dec. 15th won't ship out until January. Buy early and often!)
