My brother took the print home to Texas. About a month ago he sent me a high-resolution scan of the aged image. I decided it was worthy of restoration, so I've been working on it on and off, mostly during lunch breaks.
I think it looks pretty good now. Maybe in the future I'll add color, but I'm not real sure how good that would turn out. In the meantime, check out the restoration images.
