The match ball used for the Argentina v Germany FIFA World Cup Final played at the Estadio Azteca, Mexico City, 29th June 1986, offered with a signed letter of provenance from the Brazilian FIFA match referee Romualdo Arppi Filho, the ball autographed by Romualdo Arppi Filho and his assistants Erik Fredriksson and Bernylloa Morea the white Adidas Azteca ball is formed of 32 pentagonal panels with a sinuous black & white design inspired by the architecture and murals of the Aztec Civilisation that flourished in central Mexico through the 14th to the 16th centuries. The curvature of the Aztec motifs also acts to frame a series of white discs reserved for the printing of the Adidas branding and confirmation the Azteca is the official ball of the 1986 World Cup. The FIFA 1986 World Cup, Mexico, saw the introduction of the first polyurethane coated, rain-resistant, entirely non-leather synthetic match ball, designed for enhanced qualities on hard, rough and wet surfaces. The Azteca was hand-sewn and consisted of an outer polyurethane wearing coat and three lower layers, which mutually complemented one another with varying structures Adidas termed “Adicron.” These were intended to ensure the ball’s resistance, ability to retain its shape and be waterproof. Adidas were rising to the challenge of producing a high-performance football at World Cup venues staged at high-altitude on sun-baked pitches where turf management is extremely challenging, but at a date in the calendar that coincided with the beginnings of Mexico’s rainy season. The Adidas Azteca represented a massive leap forward for the game. In the 1986 World Cup final played on the 29th June 1986 at the Estadio Azteca before 114,600 spectators Argentina defeated West Germany 3-2 to lift the World Cup for a 2nd time. Jose Luis Brown opened the scoring for Argentina in the 23rd minute with a header after an error of the German goalkeeper, Harald Schumacher on a free-kick from the right and it stayed at 1–0 until half-time. 11 minutes into the second half, Jorge Valdano doubled Argentina's lead with a low side foot finish after cutting in from the left past the advancing goalkeeper.Karl-Heinz Rummenigge pulled a goal back in the 74th minute from close range for West Germany, his first goal in the tournament. West Germany then equalised in the 81st minute, with Rudi Voller scoring with a header from close range. Although Diego Maradona was heavily marked by Lothar Matthaus throughout the game, his pass to Jorge Burruchaga in the 84th minute allowed Argentina to regain the lead at 3–2 when he slid the ball past the advancing goalkeeper from the right and into the corner of the net.
