As you say (except for the tax deduction - although something tells me a Rockefeller probably has enough of those already) the tapestry was already a reproduction of an original. As bigjoey noted, you could get a very straight forward computer weaving if you wanted a tapestry. Oh well, I suppose the family already gave the land so they thought they wanted to get the tapestry because they had also loaned that and deserved it whenever they wanted it. The U.N. could get another original antiwar work of art to place in the space where the tapestry hung. Games of the wealthy.
