Final answer:
The Sgt. Pepper album cover was created by Peter Blake and Jann Haworth. John Lennon wanted Jesus Christ and Adolf Hitler on the cover, but they were excluded to avoid controversy.
Step-by-step explanation:
The album cover for The Beatles' Sgt. Pepper's Lonely Hearts Club Band was created by the British pop artists Peter Blake and Jann Haworth.
They were commissioned by The Beatles themselves and worked in collaboration with the band and art director Robert Fraser.
The cover features The Beatles in costume as the Sgt. Pepper band surrounded by a large group of life-sized cardboard cutouts of famous people.
John Lennon had a list of people he wanted included on the iconic album cover. However, not all of his choices were used. He requested several controversial figures, including Jesus Christ and Adolf Hitler.
These figures were ultimately not included, likely due to their potential to cause controversy and the band's desire to avoid offending fans. The exclusion of such contentious figures may have been a decision made by both the band and their record company to maintain public relations.
