The haul also includes five lithographs by French painter, engraver, illustrator and sculptor Theo Tobiasse and was discovered "because the seller has been having a clear out" at his Mayfair home.

A treasure trove of prints signed by Spanish surrealist Salvador Dali which had been “tucked away and forgotten” for 50 years have been found in a garage.

The lithographs cost £500 when they were bought in the 1970s and could now fetch around £5,000 when they are put up for auction.

The haul, which also includes five lithographs by French painter, engraver, illustrator and sculptor Theo Tobiasse, was discovered at a home in Berkeley Square, Mayfair, London, during a clear out.

Antiques expert Chris Kirkham, who is associate director of London’s Hansons Richmond auction house, called the find “amazing” and “surreal”.
