Gizmodo has a great gallery of photos from a design book series published by Phaidon called Pioneers, Mass Production, and New Technologies. It's a three-volume set showcasing 333 of the best designed products from the past century, including Lockheed's Blackbird aircraft, Technics' turntables, and the Etch A Sketch. Pictured here is the Ur-Leica camera, designed in 1913; it was the predecessor to the Leica 1 and one of the first cameras to take single shots using cinematic film.
