I’m new to this site so please forgive me if there is another area on Kovel’s where I could access this info more easily. I recently ran across some antique 135 film in there original metal canisters, of 1937-43 Chevrolet automobile advertisements, promotions, and training. I’m trying to find a market where I could sell them. I do know of a couple Automobilia auction sites I could take a chance on, but I’d like to have some knowledge of their value 1st. Any suggestions would be appreciated. Thanks.

I do have pix, but for whatever reason the image upload is not accepting them in spite of the proper format and size
