I think that establishing a museum of lost things would be a good business and a useful undertaking. This idea was born in my head when I lost my diary with photos dear to me, which I kept inside it. Three weeks passed, but no one returned it to me. Though - who needs such a personal stuff? So, I propose to establish a Museum of lost things. Everything found could be brought there, catalogued and kept there. And people who lost something would search it there and if successful, would pay some small sum as a reward both to the person who found it and to Museum. I am not sure that this is a chance for people who lost something really valuable to get it back. But if you lost something only of personal value, that would be a chance!
