The Argus C3 was a low-priced rangefinder camera mass-produced from 1939 to 1966 by Argus in Ann Arbor, Michigan.
The camera was the best-selling 35mm camera in the world for nearly three decades, and helped popularize the 35mm format.
Due to its shape, size, and weight, it is commonly referred to as "The Brick" by photographers.
