David Carson's Surf Film Festival poster. Carson was not classically trained as a designer and stumbled upon his talents through experimentation. His grunge type was a major influence in the early nineties. His Ray Gun magazine will always be one of my faves.
Public Space Poster. This works for me because while at first glance it may appear to be a chaotic mess, there is upon closer examination a sense of order, hierarchy, and structure. It's almost delicate, in the sense that eliminating or changing one part would throw off the rest.
