Album Covers were a much simpler matter in the early days of rock and roll.     Any old picture of the band or artist smiling and posing would suffice.      The Beatles were different.     From their first legitimate LP release, they revolutionized the value of a cover photo.   Their history as art students, friendship with the German existentialists, and understanding of the zeitgeist produced images that are nearly as iconic as what was in the grooves.     Stay tuned to Beatling About for Parts 2 and 3, the reissues, and solo cover art.
