A blog entitled Iron-bound Bucket has photos of some neat ephemera connected with Moby-Dick, including something near and dear to my heart, Melville's contract with Harper & Bros. for the book.
IBB was also kind enough to link to Ahab Beckons, for which, thank you!
("Iron-bound bucket" is an allusion to Ch. LXXVIII, "Cistern and Buckets." A very apt image for a blog about Moby-Dick, I can assure ye.)
