I had a Polaroid Swinger. Few of its pictures survive to this day. "It's more than a camera... it's almost alive! It's only nineteen dollars... and ninety-five!" In those days this was not cheap. And... after _every_ picture you had to carefully take the photo by the edges, then open the film canister of the special Polaroid photo preservative and take out the foam sponge and carefully wipe it across the photo a couple of times for complete coverage and then wait half a minute for it to dry before doing anything with it. Sorta lessened the spontaneity of owning a Polaroid.
