A set of keys from the Titanic are among the highlights of Christie's Out of the Ordinary sale.
The lot is being consigned by David Gainsborough Roberts, whose wildly eclectic collection is the stuff of legend.
The keys are made from brass and come attached to a key ring stamped "TITANIC".
They are expected to sell for ?�7,000-10,000 ($9,163-13,090).
In 2007, the key that unlocked the binocular chest in the Titanic's crow's nest sold for ?�90,000 ($117,810).
A rare photographic postcard of the Titanic discovered in a Bristol charity shop is selling on eBay.
Several items from Roberts' collection star in the London auction on September 14. A Stetson hat that the people of Calgary presented to Winston Churchill is expected to make ?�4,000-6,000 ($5,237-7,856).
A headscarf and agal (the band that attaches the scarf to the head) owned by Lawrence of Arabia is another fascinating bit of headgear featured in the auction.
It's expected to make ?�3,000-5,000 ($3,930-6,550).
David Gainsborough Roberts said: "After collecting for over 40 years the time has finally arrived to share my collection with the world.
"I hope my insatiable appetite for the curious, the famous and the infamous will inspire a new generation of custodians."
Gainsborough Roberts is also selling off his comprehensive collection of Marilyn Monroe memorabilia at Julien's Auctions on November 19.
