Mexico released on 13 December 2013 a single stamp to mark 25 Years of CONADE, or Comisión Nacional de Cultura Física y Deporte, or National Commission for Physical Culture and Sport, in English. The stamp features cycling, taekwando, boxing and athletics, with the silhouette of Mexican female athlete silhouette, Ana Gabriela Guevara Espinoza (born March 4, 1977, in Nogales, Sonora), a retired bemedallioned track and field athlete who became a Mexican Senator. A central circle features scientific methodology for monitoring athletic performance and body vital signs, hence the stamp background is decorated with biorhythmic graphs with various icons; one of these icons, the top one on the left features a double helical representation of DNA.
