Below are three calendars that I own. The first is from June 1977 and the painting is a combination of Houdini's 1903 Amsterdam Jail Break poster and one of his famous 1903 "nude" publicity shots.
"Escape from Prison when Manacled in Handcuffs and Irons."
The next calendar is from August 1977. The painting here is taken from a photo of Houdini's 1908 Suffragettes Challenge. Despite the caption, I don't believe the sheets were doused with water for this particular test, but this is still how a "wet sheets" challenge would look.
"The Challenging Release From Wet Sheets"
"Just When You Think There's No Escape..."
It's possible there was a variant of this last calendar that shows Houdini free of the straitjacket using the painting below.
"Something Makes it Happen!"
To see some of the other calenders, check out The Celebrated Straitjacket Release (July 1977) and The Perilous Escape From the “Spanish Maiden (September 1977) at Joe Notaro's Harry Houdini Circumstantial Evidence. Next Sunday, October 1st, Joe will share another, The Spectacular Release From the Cannon Wheel (October 1977).
Below are links to more Houdini adventures in advertising.
UPDATE: A recent Haversat & Ewing auction provides a look at some other Kinesed calendars.
