Jan and Cora Gordon, A 1922 First Edition Cover
The dust jacket of the first edition has a delightfully simple design, showing a torero running from an enraged bull. Here it is:
The image represents the "taunting of the unwilling bull" in a Murcian bullfight (pg 101). "The toreros flapped their faded cloaks at it, but whenever the bull was tempted to charge the man ran for safety and crammed himself through one of the bolt-holes in the palisade."
