Those of us who are Polaroid users, let's go out with a parade, shall we?
This exchange has one simple rule: you must use Polaroid film and send a Polaroid print. The print can be a transfer, emulsion lift, historical process print from Type 55, or a bona fide real Polaroid snap of your choice. In can be sent as a postcard, matted/mounted, whatever.
I don't know how many people we'll get, so I'll see how to group this up once I get numbers. Sign up here and PM your name and address too.
