19531581571953. A notable portrait presented to a prominent early supporter Inscribed by the president "For Senator William A. Purtell with best wishes and warm regard from his friend Dwight D. Eisenhower"; an appealing image of a pensive Eisenhower by renowned Capitol Hill photographer George Tames taken in the White House as Eisenhower announced the truce ending the Korean War. Purtell 1897-1978 served as Republican Senator for Connecticut in 1952 and from 1953 to 1959. He was one of the earliest Connecticut Republicans to support Eisenhower's run for the presidency. In turn Purtell's success in the November 1952 Connecticut senatorial election rode on the back of the strong public support for Eisenhower in the simultaneous presidential election; Purtell allied himself closely to Eisenhower's campaign platform. "A strong supporter of President D. Eisenhower's policies Senator Purtell was also a staunch American who liked to say: 'we have the finest country the finest system of society and the finest government in the world'" New York Times obituary 1 June 1978. The photographer George Tames 1919-1994 worked for the New York Times on Capitol Hill and in Washington from 1945 to 1985 taking many shots which became iconic. He took the photograph after Eisenhower's joint radio and television address to the nation announcing the signing of the Korean Armistice 26 July 1953. Interestingly this image would have been familiar to millions of Americans through its use on the 6 cent stamp issued in 1970. Official photograph taken by George Tames 358 x 280 mm copyright notice to verso stating reproduction by the Signal Corps of the US Army. Dark oak frame with conservation acrylic glazing 427 x 351 mm. Slight cockling inscription a little faded but still clearly legible very good. unknown

".because this possible peril existed Vice President Nixon and I in consultation with the Attorney General prior to my 1956 operation reduced to memorandum form our understanding as to what would be the Vice President's role in the event of a Presidential disability." - former President Dwight D. Eisenhower. The Twenty-fifth Amendment to the United States Constitution clarifies the presidential line of succession and eliminates ambiguity about the role of the Vice President. As President Eisenhower noted in his preface his signed agreement with Vice President Nixon did not have the legal authority to make Nixon the president if Eisenhower had become incapacitated during his surgeries. The death of President Kennedy brought new focus on the presidential line of succession with legislation for the Twenty-fifth Amendment proposed by Senator Bayh in 1965 and ratified by the states in 1967.

250444/4/52. <blockquote><p>Ike signed this as president and sent it to a Navy veteran</p></blockquote><p>On April 4 1949 twelve nations from Western Europe and North America signed the North Atlantic Treaty in Washington D.C. A key feature of this treaty is Article 5 in which the signatory members agreed that ""an armed attack against one or more of them in Europe or North America shall be considered an attack against them all.†Initially however the alliance was not very well prepared to carry out the mission of defending its territory. In addition to grave shortages of troops and equipment there was no command structure to direct the overall defense of Western Europe just committees - known as ""Regional Planning Groups"" - that were charged with drawing up plans for the defense of their regions.</p><p>The 12 original members were the United States Canada Britain Belgium Denmark France Iceland Italy Luxembourg the Netherlands Norway and Portugal.</p><p>All this changed after the outbreak of the Korean War in June 1950 which raised fears that Europe could face a similar threat over divided Germany. The nations of the alliance agreed to increase their defence efforts and began working on the creation of an integrated military command structure with an overall commander for NATO forces in Europe.</p><p>Selecting the first Supreme Allied Commander Europe SACEUR was easy since everyone's first choice was the popular and respected U.S. Army Gen. Dwight D. Eisenhower who had led allied forces in Europe during World War II. On December 19 1950 the North Atlantic Council announced the appointment of General Eisenhower as the first Supreme Allied Commander.</p><p>In 1952 Greece and Turkey joined in the alliance's first expansion.</p><p><strong>Document signed</strong> by Dwight D. Eisenhower first Supreme Allied Commander of Nato stamped April 4 1952 signed as President in February 1957 the first day cover honoring NATO along with the first NATO stamp honoring NATO.
