Here's an older illustration reprinted (with a slight revision) in the brand-spankin' new second printing of Graphic Classics: Robert Louis Stevenson (Eureka Productions, USA) depicting a scene from Treasure Island and the pirates' Yo Ho Ho' song.

Graphic Classics are a great series of books: classic literature reinterpreted by the finest illustrators and comic artists. Er, and me. Just have a look at some of the names above... Johnny Ryan, Hunt Emerson, Roger Langridge!
Above is the cover page for the 'Verses and Fables' section, but the book also features Treasure Island and The Strange Case of Dr. Jekyll & Mr. Hyde (by Simon Gane and Michael Slack)
Grab a copy from Graphic Classics. There are also lots of other titles showcasing other authors such as H.P Lovecraft, Jack London, Ambrose Bierce, Mark Twain, Bram Stoker, Edgar Allen Poe and more (the last four I've drawn for, too).
Thanks for looking!
