I think this picture is really interesting. It's 3 separate photos developed onto one paper. Doing this would have taken some time & it would have been extremely hard to square each photo. If you look closely, the center photo is pretty even but the side photos seem to stretch up & out at the corners.
The photo was also folded accordion style, matted on a piece of black card stock & then carried around in a wallet. Because it had been stored in the dark wallet, it sustained very little fading but was very worn.
To fix this photo, I first corrected the discoloration & then squared up each photo & removed all bends & creases. After that I worked on removing the scratches & the portions that had become worn.
