Watergate, President Nixon's resignation, and the swearing in of President Ford were the big stories of 1974. U.S. Commemoratives honor Robert Frost, Skylab, Mineral Heritage, American Revolution Bicentennial, the Legend of Sleepy Hollow and more! The glue on America's first-ever self-adhesive postage stamp caused yellowing – so it was unpopular at the time. Now it's an important part of America's postal history.
