Among the attractions will be a two-headed calf, a $1 million Swarovski crystal-covered Mini Cooper, a genuine 16th-century iron maiden, a trio of shrunken human heads from Ecuador and a 13-foot-long Tower Bridge made of wooden matchsticks, the company said.

The museum dedicated to oddities is to open in London's West End at 1 Piccadilly Circus this August. It is expected to feature more than 500 exhibits.

"The Ripley's Believe It or Not! Museum will not only be unique, but it promises to be the most incredible visitor experience in London. There's nothing like it. We're looking forward to shocking visitors from all over the world," Jim Pattison, Jr., president of Ripley Entertainment Inc., said in a statement.

Additional strange items on display include a portrait of Lady Diana made of laundry lint from a clothes dryer, a copy of "The Last Supper" painted on a grain of rice, the famous sweater worn by Marilyn Monroe during her last photo shoot on the beaches of Malibu, a mummified man and a moon rock.
