According to Michigan Day by Day, the date of this clipping is November 20, 1916, which would mean Houdini did this stunt on November 19, 1916. However, that's problematic as Houdini was in Columbus on this date. His week at the Empress Theater in Grand Rapids began on November 27. So I'm thinking the website made an error. However, I've been unable to accurately date this clipping or the escape as the Herald and other Grand Rapids papers are not on newspapers.com.
Any research bloodhounds want to take up the search and help me nail down the date of Houdini's Grand Rapids straitjacket escape?
The Grand Rapids Savings Bank building still stands today. It was built in 1916 and listed on the National Register of Historic Places in 1990. We love a surviving Houdini location!
UPDATE: Our good friend Gary Hunt has solved the mystery. This stunt took place on Wednesday, November 29, 1916. Thank you Gary!
