Young or old Elvis? That was the question 20 years ago when the U.S. Postal Service considered artwork for the Elvis stamp. The Postal Service put the vote to the public and controversy soon followed. Members of Congress debated the worthiness of an Elvis stamp, then-presidential candidate Bill Clinton weighed in, and the whole thing became fodder for cartoonists and late-night comedians, according to the National Postal Museum.
Elvis Mania paid off and the Elvis stamp went on to become the most popular U.S. commemorative stamp of all time.
