Here's a cool one. Will Eisner's pre-Spirit Sunday comic strip that's sort of a cross between Treasure Island and Captain Blood. My 1986 Kitchen Sink Press edition of the book is BIG, measuring 10 1/4 by 14 1/2 inches. It was reprinted in 2002 by Dark Horse as an entry in the Will Eisner Library (with a new cover), but unfortunately shrunk down to 7 x 10 inches. Eisner was only 20 when this strip began in 1936, and used the pseudonym Willis Rensie, but there are many fine panels that hint at the wonders to come in The Spirit.
