Front: Benito Juárez in stern three-quarter profile, high collar and dark coat, filling the right-hand third. Centre left, the Mexican coat of arms — the eagle on the nopal, snake in beak, framed by oak and laurel. Beneath it the place and date line, "México D.F. 26 Mar. 2002", with signatures for the Junta de Gobierno and the Cajero Principal. A clear stepped window sits at the left edge, "20 VEINTE PESOS" along the foot.
Back: The Hemiciclo a Juárez in the Alameda Central of Mexico City: the seated Juárez in white marble flanked by a winged figure of Fame holding a laurel wreath and a robed woman with a torch, the semicircular Doric colonnade sweeping behind. A recumbent bronze lion lies at the left. "HEMICICLO A JUÁREZ" is lettered below, with "VEINTE" bottom left and a second clear window, carrying a ghosted 20, at the right.
Mexico's first polymer note, introduced in 2002 and circulating through the middle of the decade until a revised 20-peso polymer design, still built around Juárez and the Hemiciclo, took over from 2007. The denomination was reworked again in 2021 for the current series, which drops Juárez altogether.
