The stamp issued by Guyana in 1986 "Commemorates the Achievements of L.F.S. Burnham O.E., S.C. Executive President of the Co-operative Republic of Guyana 1980-1985." The design features a picture of Linden Forbes Sampson Burnham, the first president of Guyana. "O.E." designates a recipient of the "Order of Excellence," an honor in Guyana. "S.C." may identify him as a "Senior Counsel." Also featured are an outline map of Guyana and three flags. The middle flag is the flag of Guyana. The one with red, black and green stripes, in the back, may be the Pan-African flag (see http://en.wikipedia.org/wiki/Red,_black_and_green_flag ). I have not been able to identify the flag in front with light purple and white bars, a palm tree, and an alligator.
