Thanks you two. I have scanned it but my printer really isn't up to scratch to make a good print.
I saw an advert outside one of these high street places a few years ago, that said that they could restore old photos, removing creases, etc. It looked like a really professional job, but the place has closed down now.
As regards a silver halide print ...yes this is probably what I want. The copies have to be fade proof and really good quality. Its only about 3 inches square, so I am hoping that it could be enlarged slightly as well. I don't mind paying a premium, as long as its the best that I can get.
