i hate to say it but.....i'm suspicious about this poster. a few years ago there were a bunch of 'retro-knockoff' posters done and this definetly seems in that style. i'd even bet that this is a photo of 'the godfather' post-68.
thanks guys* i kinda went the extra mile for this one. at fs2 i met a woman who asked me a bunch of questions about how i decide on what bands get an original illustration. i told her that the time/idea factor was the main reason but then jokingly added '...so if i'm hung over and the band sucks they just get clip art'. she then introduced herself as the manager for 'yonder mountain' ( last time they played the b.u.t. i did a clip art poster).
