The Beatles are back, in an astonishing series of photos that have never been seen before -- and that have fans of the Fab Four jumping for joy.

The treasure trove of 500 unpublished snapshots of John, Paul, George and Ringo were discovered in the archives at Dundee University in Scotland. 

The pictures, which capture the lads from Liverpool at the height of their '60s fame, were found on Saturday -- which also happened to be the 40th anniversary of the Beatles' first single release, "Love Me Do." 

The photos, taken by Hungarian photojournalist Michael Peto, show the boys relaxing between takes during the shooting of their second film, Help

They were given to the university more than 30 years ago and forgotten. The school says it will now show them to the world in an upcoming exhibit.
