John Lennon Throws Metal on Cover of Yellow Submarine Album

Snagged this one from the Huffington Post

The Beatles are credited with being the first to do many things such as printing lyrics on a pop album, creating music videos and holding a stadium concert, but most bizarre is their role in the “devil horns” hand gesture taking off. John Lennon’s cartoon figure on the Yellow Submarine cover is apparently the first time the symbol was on the cover of an album and is one of the earliest instances associated with a rock band, ever.
