The poster came from the collection of Dorothy Dietrich and Dick Brookz of the Houdini Museum in Scranton, who own a complete set of all 14 posters from the serial. An Episode 3 ("The Water Peril") has never come up for auction before.
The auction contained several unique and desirable Houdini rarities. A cabinet photo of Houdini and his mother fetched a remarkable $16,380. This appears be an all-time record for a Houdini photo at auction. A "King of Cards" poster brought in $11,700. A letter on unique stationary in which Houdini talks about his bi-plane in Australia went for $10,852. A letter to Will Goldston in which Houdini discusses an early injury took in $7,575.
One item that I had my eye on was a business card for Houdini's first chief assistant Franz Kukol. But it looks like it caught the eye of others as well. It beat the auction estimate of $250-$300 and went for $2,661. (All prices include the 17% buyers premium.)
