This selection of approximately 60 anonymous vernacular photographs from the 1920s to the 1960s teases the eye and delights the mind. Cut loose from their original context but infused with the aesthetic spirit of their time, these unintended and unexpected masterpieces often call to mind the work of master photographers such as Henri Cartier-Bresson, László Moholy-Nagy, and Robert Frank. Drawn from the collection of Thomas Walther, these surprising images shed new light on one of the most prolific and eccentric artists of our century: "Photographer Unknown."
