The album Help! by the Beatles shows the Fab Four doing semaphore.
As you look at the front cover the first things that you'll notice are the poses that the Beatles are standing in. These are semaphore characters. It would be assumed that these would spell out 'HELP' but for some reason they don't; spelling instead the letters 'NUJV'. What could this stand for? Well, it's been suggested that these four letters could stand for 'New Unknown James Vocalist'. Perhaps this is the Beatles subtley telling us that 'James' (Paul's real first name) has been replaced by a new unknown? Incidentally, if the photo on the front cover is mirrored the Beatles spell out the letters 'KPUN', so the theory that they were spelling out HELP until the photo was flipped in production is false.
