The Union of South American Nations (UNASUR in its Spanish acronym) is an organization formed by the 12 independent nations of South America (with Mexico and Panama as associate members).
Although apparently unofficial, a flag appears on most of the meetings of the organizations (like that, that occurred this month).
The flag is blue with a white logo. The use of logos on flags is common between international organizations, but may result in bad results, specially if the logo is too abstract or two complex; what's not UNASUR flag's case. The logo, similar to a whirl, remembers the shape of the South American continent. Reported variants have the "UNASUR" word either above or below the logo.
The flag is considerably different from the proposed flag given by Peruvian then-president Alan García to the president of Chile and then pro-tempo president of UNASUR, Michelle Bachelet, on its constitution summit.
The flag presented by García was red, with a golden silhouette of South America inscribed in a golden ring. That flag was inspired by a design by his party's founder, Victor Raúl Haya de la Torre (1895-1979). Haya's design, however, had the map of the whole Latin America instead of South America only.
