Richard Nixon meets RoboCop in 1987.
From the newspaper caption:
Richard M. Nixon is escorted by RoboCop at a national board meeting of the Boys Club of America. The RoboCop character was on hand to call attention to Orion Home Video’s RoboCop RubOut promotion. Sweepstakes tickets, packaged with each “RoboCop” cassette, offer a number of instant prizes for retailers as well as $25,000 in donations to the Boys Club. The sweepstakes is part of a $3 million promotional effort launched by Orion in conjunction with the action-adventure film’s video release. The cassette will be available in video stores beginning Jan. 28 for a suggested list price of $89.98.
This makes Richard Nixon the only human being to have met the two greatest crimefighters in U.S. history.
