The Beatles Map of Liverpool was published in 1974 to commemorate the buildings and places where the Beatles started their career.
As noted on the Liverpool Museums website:
Featured here is one of the first Beatles maps of Liverpool that was ever produced. It was produced by the City of Liverpool Public Relations Office in 1974 and was included in a souvenir pack entitled 'From Liverpool to the World'. The pack took the form of an album sleeve. Inside it was not only this map but also a booklet about the Beatles and their career, a Beatles poster and fan club letter, Beatles postcards and wall charts.
The project was first refused because the director of the department looked upon the Beatles, who were then arguably at their nadir, with disfavor. He unwisely did not realize, that the Beatles were by far Liverpool's best ambassadors.
