We love a good conceptual photo series, and the Kahn & Selesnick's fantastically visionary Mars: Adrift On the Hourglass Sea photography series is one of our favorites we have seen in quite some time. Envisioning an expedition and civilization on Mars, the work focuses on societies in crisis and on the brink of major change, and although the work appears alien, the DYI and recycled nature of some of the materials in each photo makes everything appear familiar.
