Wistariahurst Museum in Holyoke, Massachusetts. The exhibition is called "Houdini, Holyoke & the Sidney Radner Collection" and runs until October 31.
Sidney Radner, who died last year at the age of 91, auctioned off much of his collection in 2004, including the Water Torture Cell. But he held on to a few precious items, including handcuffs, tools, and challenge broadsides. Sidney's son William Radner now controls the Houdini-Radner rarities that are to be displayed.
The museum will host a special opening night reception tonight from 6 to 8pm. Tickets to this special event are $10. Regular admission to the gallery is $3.
The Wistariahurst Museum is located at 238 Cabot St., Holyoke, MA 01040. It was the site of last year's Official Houdini Seance. Visit their official website for more information.
