Traffic-building stunts using people as props are as much a part of the trade show experience as sore feet and tchotchkes. At the annual Chicago Auto Show, for example, women posed on top of cars as flesh-and-blood hood ornaments, while little people promoted subcompact cars. Continuing the tradition, Chrysler Corp.'s Dodge brand offered $2,000 to anyone at the 1976 Chicago Auto Show who could break the composure of living mannequin Nancy del Corral. While hundreds, such as the man pictured here, tried to upset her equilibrium with comic antics, del Corral maintained her robotic visage.
