Paul Calle (Connecticut, New York, 1928 - 2010) "50th Anniversary of the United Nations". Signed lower right. Original Mixed Media painting on Illustration Board. Provenance: Collection of James A. Helzer (1946-2008), Founder of Unicover Corporation. This painting was originally published on the Fleetwood First Day Cover for the United States 32c 50th Anniversary of the United Nations stamp issued June 26, 1995. On June 12, 1941, the Inter-Allied Declaration "to work together, with other free peoples, both in war and peace" was signed in London. This event proved to be the first of many steps toward the establishment of the United Nations. Two months later, U.S. President Franklin Roosevelt and British Prime Minister Winston Churchill endorsed the Atlantic Charter, a document that proposed a set of principles for international collaboration in maintaining world peace and security. Representatives of 26 nations -- all of which were at war with the Axis powers -- signaled their support of the Atlantic Charter by signing the "Declaration by United Nations" on January 1, 1942. This marked the first official use of the name that would ultimately become synonymous with world peace. Another step toward the development of the United Nations occurred on October 7, 1944, when diplomats from the United States, the United Kingdom, the Soviet Union and China convened to lay the groundwork for an international peacekeeping organization. The Yalta Conference -- the historic meeting that determined the disposition of postwar Europe -- was also instrumental in the United Nations' establishment. Later, the four nations that had attended the conference became permanent members of the U.N. Security Council. On April 25, 1945, the 111-article Charter of the United Nations was drafted. It was signed on June 26, 1945, and came into force on October 24 -- a date that has since been designated as United Nations Day. Image Size: 14 x 11.75 in. Overall Size: 22 x 18 in. Unframed.
