The Bogus White House Letter
RAY: Here's the answer. And there were a lot of hints. It could be Ford's incorrect address. Or maybe the White House wasn't located at 1600 Pennsylvania Avenue back then. Maybe it was 1601 Pennsylvania Avenue. But the curator knew the letter was bogus because in 1898 it was not called The White House. It wasn't called The White House until Theodore Roosevelt became President, after McKinley was assassinated. In 1898, it was called The Executive Mansion.
TOM: Get out! And it couldn't have come from The White House in 1898 because The White House didn't exist as such.
