On April 26, 2000 the USPS issued the fourth stamp in the Looney Tunes series featuring Wile E. Coyote and Road Runner. The Bugs Bunny stamp began the series in 1997, followed by the Sylvester and Tweety stamp in 1998 and the Daffy Duck stamp in 1999. Bugs continued to serve as the Ambassador for the STAMPERS youth collecting club, while subsequent Looney Tunes stamps brought additional attention to the hobby of stamp collecting. Wile E. Coyote has appeared in more than 40 cartoons with Road Runner, the speedy object of his appetite. Wile E. Coyote is a lovable antihero. His confidence and ambition never cease in his pursuit of the elusive Road Runner who, relying on an instinctive gift for survival, effortlessly thwarts all his schemes. Although Wile E. Coyote is always more humiliated than harmed by his failure to catch Road Runner, even with his faults, the audience's sympathy remains with Wile E., and the hope endures that someday Wile E. Coyote will catch Road Runner.
