        We have received a number of gift maps this week from a patron who
    is now interested in placing a value on her donation in order to
    reflect it on her tax returns. This would not ordinarily pose a problem
    as we have a large collection of catalogs and price lists. But, a large
    number of these maps are National Geographic Maps - some quite old,
    some not quite so old. My question to the list is if anyone may know
    of, or have a price-list from any company or sales agent who resells
    these types of maps? Or if none of the above are available, does any
    one know of a way to effectivly place a value on these materials. I
    know it's difficult sight unseen.
        Thanks in advance.
