With Her Head Tucked Underneath Her Arm was created in 1934.
Anne Boleyn was executed on May 19th, 1536. She didn't have anything tucked under her arms during her execution, but ghost stories about her death include references to her "carrying her head tucked beneath her arm."
Those muscles are called the triceps.
Some are held on with a nut and others have a clip underneath that has to be pulled back to that the arm can be taken off.
