I agree with kfields. Museums have more than 70% in storage. There are ones - I know what I say - who get the items as a gift, family thought they will honor them, and then the items where sold at the museum like a flea market. Other ones had them on display, but sold the original ones and replace them with fakes. Think this is not only a problem in Europe. But I will talk about the other side - the side of the collector. Know some who get full picture albums as a gift beside an item, and sold them pic by pic on ebay which means destroying history.
