Houdini handcuffs at Comic Con

A pair of Mattatuck handcuffs used by Harry Houdini are currently on display at the Profiles in History booth at the San Diego Comic Con.

The Con -- the worlds largest gathering of all things pop culture -- started on Thursday and runs through Sunday at the San Diego Convention Center. Attendance is expected to top last year’s 200,000.

The cuffs are auction lot #664. Bids can be placed via eBay. Price estimate is $7,000 to $9,000.

The Mattatuck cuffs were first sold at Butterfields Houdini auction in Los Angeles in 1999 as part of the Sidney Radner Houdini Magical Hall of Fame collection.
