A collection of shackles used by Harry Houdini (1874-1926) in his escape acts is to feature in a sale at Briggs Auction in Pennsylvania on February 21.
They will auction as a single lot with an estimate of $60,000-80,000.
The collection is presented in a velvet-lined box and consists of 12 restraints, ranging from neck and ankle shackles to padlocks, many of which show signs of water damage due to being submerged.
Houdini famously performed many of his most daring escapes underwater.
A collection of 26 padlocks used in Houdini's acts carry an estimate of $50,000-70,000.
Each of the elaborate locks originate in 12th century Europe, and featured in the film Houdini (1953), which starred Tony Curtis and Janet Leigh.
A billboard bearing the inscription "The World Famous Houdini, Master Mystifier" is valued at $8,000-10,000.
The four sheet colour lithograph displays his portrait in the top left hand corner, surrounded by bats, black cats and witches.
Last year, a new record was set for a magic poster at auction when a sheet advertising The Grim Game, a 1919 silent film starring Houdini, made $67,166 in an online auction.
We have this signed photograph of Harry Houdini dating to 1911.
Another sale of magic memorabilia took place at Potter & Potter on February 8, where a copy of Harry Dean's The Whole Art of Legerdemain made $25,000.
