The first one that I owned myself was an old Polaroid Colorpack II. It was a gift I got from a caretaker at a grade school I attended in the early 90's. The CP II was, of course, an old camera, even back then. (made between 1969 and 1972). I received the camera and two packs, which I shot myself.
Now, when the packs were gone... I had a slight problem. I had an uncle who actually worked in the Polaroid factory here in Enschede. I showed him the camera, and he unfortunately told me that Polaroid had stopped making film for it. This was around 1997 or so. I don't know if Fuji was already producing their FP100 then, and even if they were... I couldn't afford it as a teen anyway.
So, my uncle proposed a trade: he'd keep the CPII for his personal collection and gave me a 1000 series land camera - the cool white one with the rainbow - in return. I shot that a few times and even bought some film for it. Once they stopped making it... in the closet it went. I still haven't gotten around to buying some Impossible film for it, even though I pass by the factory every day
The reason for that is: I actually bought a Colorpack II again last year! When I found out Fuji had film available, I searched and found a brand new looking CPII and I've shot at least five packs with it so far.
