On October 25, 1945, President Harry S. Truman issued Executive Order 9646, which officially defined the Presidential Coat of Arms and Seal.  The eagle's head, which originally faced right toward a bundle of 13 arrows held in its talons, was turned to face left toward the olive branch symbolizing peace.  The only changes to the seal since 1945 have been the additions of the 49th and 50th stars.
