This is a poster downloaded on Tuesday March 1, 2005 from the www.delatealnarco.com website offering a US$5 million reward for information leading to Joaquin “El Chapo” Guzman, one of Mexico's most poweful drug lords, and 36 of his associates. The mystery surrounding the posters has intensified after Mexican authorities denied plastering them in three of the country's major cities. The Attorney General's office said it has opened an investigation to determine who distributed the posters, while Mexican media suggests they are part of a plan by Guzman's rivals to get to him.
