Call it the "art" of the deal.
A sketch of the Empire State Building by President Trump -- which once sold for less than $100 -- was bought at auction by a New York real estate developer and former business partner of Trump's for $16,000.
Elie Hirschfeld, president of Hirschfeld Properties, purchased the 12-by-9-inch black marker depiction of the iconic New York City skyscraper at an auction in California and online last week.
It was created by Trump for a charity auction in Florida during the time he opened his Mar-a-Lago estate as a private club in 1995.
Julien's Auctions says the piece signed by Trump went for less than $100 the first time it was sold.
In a statement Monday, Hirschfeld says he plans to hang it in his offices a couple of blocks from Trump Tower.
