These photos are pretty unique. Early in his career, Elvis allowed journalists unrestricted access. They could take candid photos like this. There’s a famous documentary of Elvis on tour that shows him goofing around and relaxing with friends.
A few years later, Elvis’ manager Tom Parker stopped it. All the reporting & photos afterwards were carefully planned and staged. They were packaging Elvis and creating a brand. The public never saw Elvis again unless it was carefully controlled by publicists.
