Unseen photos of The Beatles are to go up for sale after lying in a family album for nearly 50 years.

The photos show the band with their instruments but also between takes in off-guard moments, with one picture of Ringo Starr resting on bricks to boost his height for the cameras

The 20 black-and-white snaps have never been published and give a rare behind-the-scenes glimpse of the Fab Four on the cusp of becoming a world phenomena.

They were taken as the band filmed their first movie, A Hard Day’s Night in March 1964 at the Scala Theatre in London.

The photos show the band with their instruments but also between takes in off-guarded moments, with one picture of Ringo Starr resting on bricks to boost his height for the cameras.

Taking photos on a closed set was strictly banned to stop leaks of The Beatles’ new material, but Peter Allchorne, who was props manager at Pinewood Studios was able to wander around with his Kodak Retinette snapping away without fuss.

The photos were then put in his family album and largely forgotten about until Mr Allchorne, who lives in Preston, Lancashire, put them up for sale at auction.

The 87-year-old’s daughter, Jacqueline Griffin, said that while the world was embracing Beatlemania, her father thought they were just another band he got to know through his job.

“He was just that type of person who always had a camera round his neck,” she said.

“It was not unusual for him to be on set and taking pictures. He wanted to take snaps of one of the crew, a mate Alfie, and they were there, it was when The Beatles were on stage.

“He got to know them quite well but he was just not that interested. I think they just larked about and had a good time. He was not particularly star-struck.

“They were just four lads in a band, it didn’t really hit him.

“They are unpublished and never seen. They’ve been in a family album since 1964.

“He’s never held any value on them because he was not into The Beatles, he was just working on the films. He doesn’t have any sentimental attachment. They’re just dad’s pictures.

“He didn’t like the music, he was into jazz.”

A menu card, signed by John, Paul, George and Ringo from the band’s trip aboard the BOAC Cunard, London to New York flight will also go under the hammer at the sale.

The Fab Four were given a choice of the finest wines from the vineyards of Bordeaux along with champagne and clear turtle soup amontillado.

They were en route to the Bahamas, along with Mr Allchorne for the filming of Help! in February 1965.

A second unsigned menu card from the return leg of the journey features a misspelling of “The Beattles” – with the errant “t” expected to attract extra interest from bidders because of its novelty.

However, the photos taken of The Beatles on their Bahamas trip have been lost forever – after Mr Allchorne’s camera was stolen from the beach.

The remaining photos taken in London, along with the original negatives, have been given an estimate of €2,400 and the entire lot €12,000.

The sale will take place at Omega Auctions in Stockport, Cheshire, on May 19 and be broadcast live via www.omegaauctions.co.uk.
