In celebration of the 50th anniversary of The Beatles‘ first film, A Hard Day’s Night, the high-end U.K. publisher, Genesis Publications has put together a book called Golden Dreams. It features never-before-seen photos taken on the movie’s set by Astrid Kirchherr and Max Scheler.

In the book Astrid, who was engaged to original Beatles bassist Stu Sutcliffe and who is responsible for the Beatle haircuts, writes, “They were still young and irreverent, and they didn’t take it all that seriously. It was a laugh, as it always had been. They would lark about on set and it was a very familiar atmosphere. John [Lennon] would be cracking jokes and [director] Richard Lester would sometimes collapse with laughter. At the same time, they were professionals.”

The book is limited to 2,500 individually numbered copies, each signed by Kirchherr and Scheler.
