The album cover for Led Zeppelin II was from a poster by David Juniper, who was simply told by the band to come up with an idea that was "interesting."
His design was based on this photograph of a Division of the German Air Force during World War I. Dubbed "The Flying Circus" and led by Manfred von Richthfen "The Red Barron."
He airbrushed the photo adding the faces of Jimmy Page, Robert Plant, John Paul Jones and John Bonham taken from this 1969 publicity band photo.
He also added the faces of manager Peter Grant and tour manager Richard Cole. The woman on the album cover is actress Glynis John (the monther of Mary Poppins). Her presence of photo was a play on the name of recording engineer Glyn Johns.
Peter Grant – Richard Cole – Glynis Johns
There's a bit of a debate about the other three people on the cover. Some say that guitarist Blind WIllie Johnson is on the cover but there is only one known photo of Johnson in existence, and it is not the same photo. Any guesses???
