Polaroid Swinger Model 20 This is the "Polaroid Swinger Model 20". It comes from the series of popular and cheap "Swinger" cameras that were produced by Polaroid from 1965 to 1970. Other models of the Swinger series include the Model M-15 "Swinger Sentinel" and the Model 3000 "Big Swinger".   With a first price of USD $19.95 the Polaroid Swinger was the first truly affordable instant camera. The low price and the relative ease of use of the camera made it popular with the young adults of the 1960s and 1970s, which resulted in the sales of millions of units.   The camera is equipped with an award-winning plastic housing, a plastic lens with a fixed lens, a rotary shutter with one speed, a built-in flash for AG-1 bulbs and the exposure setting via a built-in photometer. The camera would originally use Polaroid Type 20 series roll film, which was the first instant film by Polaroid for developing outside the camera.   Although the Swinger series of instant cameras had existed only 5 years during the mid-late 1960s, the concept of a cheap instant camera with a round (non-foldable) plastic housing would be carried on with the Colorpack, Square Shooter and Super Shooter series of land cameras in the 1970s.   Towatch a vintage tv commercial for the Polaroid Swinger with a young Ali MacGraw! www.youtube.com/watch?v=h7k2uwJmwxo
