What’s special about this one in front of the D.C. Court of Appeals (Lincoln was a lawyer, after all) is it was the first public monument of Lincoln following his 1865 assassination. It was paid by District residents.
Lincoln stands on a pedestal with a bundle of sticks, which was the symbol of the law in ancient Rome. Sculptor Lee Flannery knew Lincoln so it’s a good likeness. It was dedicated in 1868.
