Background on the UN logo: http://www.un.org/Depts/dhl/maplib/flag.htm
The current United Nations emblem was approved on 7 December 1946. The design is “a map of the world representing an azimuthal equidistant projection centered on the North Pole, inscribed in a wreath consisting of crossed conventionalized branches of the olive tree, in gold on a field of smoke-blue with all water areas in white. The projection of the map extends to 60 degrees south latitude, and includes five concentric circles”.
Olive branches symbolize peace. The world map depicts the area of concern to the United Nations in achieving its main purpose, peace and security.
The use of the emblem is restricted, based on General Assembly resolution 92(I),1946,Regulations for the control and limitation of documents, and Use of the United Nations emblem on documents and publications.
