"I have never seen a portrait of my father which is to be compared with it in any way," Robert Todd Lincoln said of George P.A. Healy's 1869 painting Abraham Lincoln. The younger Lincoln purchased the painting shortly after its completion, and it remained in his household until 1939, when his widow, Mary Harlan Lincoln, bequeathed it to the White House. Today the portrait hangs above the fireplace in the State Dining Room. Carved into the mantel below is an inscription from a letter written by President John Adams on his second night in the White House: "I pray heaven to bestow the best of blessings on this house, and all that shall hereafter inhabit it. May none but honest and wise men ever rule under this roof."
