The Greatest Auction - Season 1 Episode 4 -

Today, a neon sign from a Soho sex shop lights up the arena and sparks a bidding war; a piece of Kate and Will’s wedding cake goes up for sale; will one of what’s thought to be only 5 remaining copies of Henry Beck’s redesign of the London tube map from the 1930s reach its £30,000 reserve?; and a reluctant seller brings a skeleton out of his wardrobe to go under the hammer at The Greatest Auction.
