Printed souvenir presidential Oath of Office on an off-white 8.5 x 11 sheet, signed at the top in black felt tip. In full: “I, Barack Obama, do solemnly swear that I will faithfully execute the Office of President of the United States, and will, to the best of my ability, preserve, protect and defend the Constitution of the United States. So help me God.” The Oath of Office of the President of the United States was established in the United States Constitution and is mandatory for a President upon beginning a term of office. The wording is prescribed by the Constitution (Article II, Section 1, Clause 8). The oath is typically administered by the Chief Justice or sometimes by another federal judge. By convention, incoming presidents raise their right hand and hold the other on a Bible while delivering the Oath. In very fine condition. RRAuction COA.
