----------------------------Original message---------------------------- 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.
