Alan Aldridge, the man behind the cover art for Captain Fantastic.

Alan Aldridge is the artist who created the wonderful cover for Elton John's 1975 album "Captain Fantastic and the Brown Dirt Cowboy" and he has a website that features more of his work. Among that work is this piece that apparently was done for the Bally Captain Fantastic pinball machine. I don't think I have ever seen this.
UPDATE: Click here to see pictures of a 1977(?) Bally Captain Fantastic pinball machine with the above artwork.
