Do you fancy getting your hands on an original World War Two enigma machine? How about a full set of armour?
Christie's Out Of The Ordinary sale brings together a bizarre array of lots that don't easily fit into the auction house's more traditional collections.
Among our favourites is an oak Capture Chair with leg locking devices, (estimate: £25,000-35,000), which can trap anyone who sits in it with the metal leg-locking bars hidden inside the chair. The captive can only be released by using a mechanism at the back of the chair.
There's also a dog skeleton which has been covered in 60,000 Swarovski crystals and platinum by artist Moogstones, in what could be considered a less extravagant version of Damien Hirst's £1million diamond-encrusted skull, For The Love of God. The sparkly skeleton is expected to sell for £20,000-£30,000.
With prices ranging from £500-£120,000 many items are likely to be out of the reach of the average pocket, but there's a chance to see the lots at the free-to-enter saleroom.
Visit Christie's at 85 Old Brompton Road in South Kensington, until 2 September. Opening hours are 9am-5pm weekdays, 11am-5pm weekends. Free to view (but don't cough during an auction).
