This is a very interesting find. Based on a visual look up, it is telling me based on Japanese writing that it is a roll of Japanese Aerial Infrared Film. I picked it up curious to what it was, and opened it, being the person that had it had no clue. I unrolled it about 24 inches or so. Was solid black on one side, green on the other. That may have deemed it unusable, however there was plenty left still rolled up, so not sure if that would be or not. Anyways, leaving all that to you the curious collectors to find out on your own. This is being sold AS IS. The metal canister measures approx 8" x 2 1/2", and roll is approx 1 3/4" thick. I take pride in my pictures, and are a valuable extension of my description.
