Smithsonian: National Postal Museum

Of all the Smithsonian museums, one of the least known, aside from fervent philatelists, is the National Postal Museum. But step inside, and you’ll be amazed at all the unexpected treasures, such as Roberto Clemente’s World Series memorabilia, a leather jumpsuit worn by Amelia Earheart and a pocket watch from the Titanic. We put a creative team in place to pitch the Postal Museum on a spec advertising campaign aptly titled America’s History Is in the Mail to promote its unknown riches.
