Letter from Pedro J. Gonzalez to Roberto Fierro Villalobos. In the top left corner of the page are two icons, the higher of which has the text "Central Popular Revolucionaria" and "Mexico" in its design while the lower icon has "PRI" printed within its shape. Below the icons is a narrow column of text while to their right is the title "Central Popular Revolicionaria" followed by smaller words. The rest of the page is occupied by a wide column of paragraphed text that continues onto the back of the page on across both sides of two additional pages. The third page also has handwriting on its back.
