I grew up thinking that on the cover of the Beatles Help! album, they were spelling out the word HELP in semaphore. Maybe you did too ... but we were fooled.

According to the story they originally planned to do that but when they got to the photo shoot, the arrangement wasn't very pleasing to the photographer's eye. So after some adjustment, they ended up with something completely different on the cover.

Interestingly, the UK and US versions aren't even the same. On the UK version (below left) the Fab Four appear to spell NUJV. However on the US version they're shown in a different order, seeming to spell NVUJ.
