The seller was from the Sutton Coldfield area and the print went to a private buyer in the UK, the auctioneers said.

But then some people started asking questions about how it ended up under the auctioneer's hammer.

He also contacted the auctioneers, who emailed the seller.

Jonathan Torode, from the Kings Langley-based auctioneer, said: "We are thrilled to be able to offer the opportunity to acquire one of the rarest stretch toys in existence."

The auctioneer said it is now the most expensive toy of its kind in the world.
