On July 28th, 1968, Don McCullin spent a whole day photographing the band. There was a need for contemporary publicity images and the band and they visited a variety of locations from the Thames docks to Paul's garden.
On 22nd August, 1969, The Beatles all turned up at Tittenhurst Park - John's house in Ascot, at the time - for what turned out to be their last set of photos taken together.
Photographers Monte Fresco and Ethan Russell took these now iconic images.

It's sometimes hard to remember that imagery as iconic as the Sgt. Pepper album artwork began, like everything, as simply an idea - and one that took trial and error before getting it just right.
These photos are a behind-the-scenes glimpse at the cover-shot 'could-have-beens', as well as the people and paint-pots it took to put it all together.
Practice makes perfect.
