Iain Alexander, a British painter who has exhibited in Palm Beach, Florida, designed a proposed $250 bill recently sent by the Trump Administration to the Treasury Department.

In an interview with the Washington Post, Alexander said that Trump had reviewed his design and gave the okay for adding the colors of the US flag and a logo commemorating the 250th anniversary of the nation’s founding, which is being celebrated this year. “He likes to call me his favorite British artist,” Alexander said of Trump.
