Hi, my grandfather was Mickey Mantles Dr. For a while. He was also a photographer. He died in 1959. I have recently discovered my grandfather left behind several photos "original negatives included" of Mickey hitting home runs and other plays. After months of google search I believe I have pinned down they were taken at municipal park stadium Ks in the 50's.
So I'm trying to figure out if they have a value? Should I sell them? Insure them? Or just enjoy the heirloom? Any help in the right direction is appreciated.
These photos have never seen the light of day by any one other than my family. The negatives are in FULL COLOR and close, crisp, and mint condition. I'm concerned if somebody wanted to buy them, I'm sure they wouldn't want the pics plastered all over the web, so I have been hesitant to post them anywhere. I just don't know what to do...if anything. Thanks for your help
