Buying Type 42 PolaPan roll film

[Thom05]

Hey all, I was wondering if anyone could help point me in a direction where I could find some type 42 film, even if it's expired.

Hi Thom,

Sorry, I'l kidding you. This type of antique Polaroid B&W roll film is so old that the boxes that have a beautiful appearance/shape remain in the windows of the museums. You may be able to find them in quite rare flea markets and or on well-known sales sites.
Good luck!
