Warren Chappell, who illustrated the Norton edition of Moby-Dick, (see earlier post) studied and taught there.
His Ahab is a left legged fellow, whose peg leg is somewhat elegant and thin. The pea coat, floppy hat and beard give him a salt look.
Also interesting is the fact that there is no hint in this image or any of the other numerous images of Ahab in the book, of a psycological storm brewing. He seems oddly an everyman Ahab.
