As a museum professional I can say that among our collection there are a few reasons why that occurs. With our Meso-American clothing it is generally a function of light influenced degredation, and with our egyptian collection, more specifically the mummy it is out of respect for the body. But I would say that the Loan permissions and postcards are a valid point as well.
