Poster has a black and white photograph in the center of a Native American on horseback looking up to the sky. Around the photo is a black border with green vine design. The poster reads, "10th Biennial Wilderness Conference/ April 7 8 9 1967 San Francisco Hilton Hotel/ Sponsored by the Sierra Club/ 1050 Mills Tower San Francisco." [This is an excellent example of the convergence of rock/counterculture aesthetics and more traditional movements. e.g. the conservation movement. Native American iconography had already seen a lot of appropriation in rock and counterculture posters. This poster is a variant of #2010.54.684. -LMC]
