I haven't done too much photo restoration lately, and, in point of fact, I have never done enough to become proficient, but here is a recent scan of Cuppa sitting on Santa's lap in the early fifties.

I did this for her birthday, just last week. I had greater ambitions, perhaps a collage, but when push came to shove, this is the only photo that I got scanned and fixed.
