New of the stunt was syndicated. Below is an account from the The Philadelphia Inquirer, August 3, 1916.
Below is a nice look at the Garden Pier theater, which was built in 1913. Houdini was playing some rare summer dates in 1916. He had just completed a run in Brighton Beach. You might recall that during this Atlantic City engagement he teased the idea of fighting a live shark.
Thanks to Jesse Leeds-Grant for this discovery and tip. And thank you to the Atlantic City Heritage Collections Archive at The Atlantic City Free Public Library for allowing me to share it here.
