The Terror Island ad above claims:
He has leaped, manacled off the Eiffel Tower and the Brooklyn Bridge, releasing himself before reaching the ground.
One of the FACT versus FICTION questions from the Houdini Miniseries Quiz was:
Houdini once jumped off the Brooklyn Bridge?
and the answer was:
Fiction, he leapt off Detroit’s Belle Isle Bridge, among others, but never New York’s favorite landmark.
Well, what about the Eiffel Tower? According to a Grim Game Ad, I blogged about a couple years ago:
As an instance he was once handcuffed, tied and sewn in a canvas sack, and thrown from Eiffel Tower, Paris. Halfway down Houdini was out of the manacles and the sack and clinging to a parachute.
Of course that same Grim Game Ad also claimed:
He was thrown from Brooklyn Bridge locked in a steel safe. He came up in one minute.
So take the ads for what they are.
