Michael Peto's pictures capture the band at the height if its fame in 1965
Mr Peto left the 500 Beatles images to the University of Dundee when he died in 1970
The rare photographs are especially unusual in that they were not posed unlike most photographs taken at the same stage in the band's career
The highly personal images were taken during the filming of Help!
Mr Peto's pictures give a remarkable behind-the-scenes look at the band
The exhibition of Mr Peto's work will run at the University of Dundee from 26 May to 11 July
