Dirk and Carol Fowler (a.k.a. F2-Design) are pretty much the king and queen of concert posters. The Texas-based duo has over 160 stunning gig posters in their portfolio, including this minimal letterpress print for a Willie Nelson concert in 2008. They do sell their concert posters on their site, but unfortunately this one is sold out (I’m not surprised). However the die-hard Willie Nelson fan can still buy it from Lone Star Posters ($100).
