In the 70s and 80s, Polaroid's founder, Edwin Herbert Land, provided prominent artists with custom-made cameras and film not available to the public. Big names like Andy Warhol, Robert Mapplethorpe and Ansel Adams were fans of the limited-edition technology and used it often, resulting in the 44,000-piece collection of Polaroid masterpieces now owned by Vienna-based WestLicht Museum of Photography. They're displaying 350 of the photos now in Austria, but if you can't catch a flight in time to check it out, Flavorwire has a preview. Link
