There is a book on museum law on the market, but I forget the exact name. I
suggest you check w/an attorney, an accountant, or even a regional IRS
office. I'm sure they could tell you the law(s).

What is the rule on giving gifts to the museum at the end of the year and
>being able to take the income tax deduction? Does the gift have to be in
>possession of the museum by the end of the year, or is a verbal or written
>proposal of the gift (and perhaps written agreement to accept) necessary for
>the deduction to be honored. Thanks for your help.
