A friend of mine is a keen amateur photographer. He is nearing retirement age with worryingly low funds. However, down the decades he has attended many Olympic Games around the World and got a unique collection of photos from them, obviously including countless great sports stars. As he's not a trained or pro photographer, they're not technically great pictures but there's plenty of very good ones. Can you suggest what my friend can do with his Olympic archive that could make him decent money? He's looked into a book, but apparently they don't tend to sell well. Any other ideas?
