To build his skyscraper, Trump first had to knock down the Bonwit Teller building, a luxurious limestone building erected in 1929. The face of the building featured two huge Art Deco friezes that the Metropolitan Museum of Art wanted to preserve. The museum asked Trump to save the sculptures and donate them, and the mogul agreed—as long as the cost of doing so wasn’t too high.

But then, according to journalist Harry Hurt III in his book Lost Tycoon, Trump discovered that taking out the sculptures would delay demolition by two weeks. He wasn’t willing to wait. “On his orders, the demolition workers cut up the grillwork with acetylene torches,” Hurt wrote. “Then they jackhammered the friezes, dislodged them with crowbars, and pushed the remains inside the building, where they fell to the floor and shattered in a million pieces.”

The art world was shocked. “Architectural sculpture of this quality is rare and would have made definite sense in our collections,” Ashton Hawkins, the vice president and secretary of the Met’s board of trustees, told the New York Times. Robert Miller, a gallery owner who had agreed to assess the friezes, told the paper that “the reliefs are as important as the sculptures on the Rockefeller building. They’ll never be made again.”
