I have 2 negatives from before 1979 because thats the date of the round shipping tube there in and were shipped or shipped from kodak rochester,ny im guessing. These are like 3x5 foot color negatives. One is a photo of a tribe member with like aztec ruins in the background. The negative says this side up on the sides.
What is this , and is it worth alot? I can take a pic of it if needed
