In the Watergate scandal, he drew Richard M. Nixonnailing himself to a cross. He stood Dick Cheney at a vast graveyard of veterans, saying, ''For seven years, we did everything to keep you safe.'' And on the frieze over the Supreme Court, he etched the hallowed words: ''Of the insurance co's. By the insurance co's. And for the insurance co's.'' Paul Conrad's rapier editorial cartoons in The Los Angeles Times, The Denver Post and other papers slashed presidents, skewered pomposity and exposed what he saw as deception and injustice for six decades. Subjects squirmed. Readers were outraged and delighted. And he won a host of awards, including three Pulitzer Prizes. [ABSTRACT FROM PUBLISHER]
