construction, the bill for the 1972 Olympics increased from the original estimate of $3.5 million to $63 million on the roof of the Olympic Stadium alone. The overall bill of $750 million, which was more than three times the amount Mexico spent on the 1968 games, resulted in unofficial posters of Waldi using the Olympic Tower as a Fire Hydrant. To coincide with the Phaidon Press publication of the first monograph of Otl Aicher's work, an exhibition of his work on the 1972 Olympics was shown in London in 2007, including his work involving Waldi.
