This is a lot of microfilm photos of automobile parts. There is Chevrolet, Pontiac, Oldsmobile, Buick, Cadillac, and GMC. These are color coordinated. There are many of these that are shown out of envelopes. There many, many more still in the shopping envelopes. The reddish color is Oldsmobile. The blue is Buick. The brown is Cadillac. Light brown is GMC. That’s what I have showing in the pictures. Many more are in the envelopes. Envelopes have been opened. Each packet in the rows has anywhere from 4-27 sheets of microfilm each with so many pictures that I will not count them. There are thousands of pictures with many microfilm sheets. Please look at the pictures. As far as I know, all of these are in mint condition. I could be wrong.
