"Perot Foundation purchased the manuscript in 1984 for $1.5 million and loaned it to the National Archives in Washington, D.C., where it had been on exhibit until earlier this year."
Interesting. So, all the costs since 1984 would have been paid by us taxpayers - exhibiting - maintaining temp/humidity, security, insurance, transport, and personnel salaries - guards and the like. And, perhaps that is somehow transferable to the Perot Foundation to deduct from the gain?
