I took a black and white school class photo with my wife in it when she was 11. I cleaned it up on Photoshop and enlarged it a bit and then had it made into a jigsaw of 500 pieces. It cost very little to do this and I think it was an offer that Aldi had at the time so was less than a tenner to have the jigsaw made. My wife - now 74 - loved it and put it together in about three days and remembered many of the other kids on it too. It has now been framed and is on the wall where she can often see it and smile. I sometimes take it down and we go through the names of her schoolmates and talk about them and whether she still sees any of them etc. I'm now considering which old photo to try next.
