Before he (and his wife!) created a world-famous mouse, Walt Disney was already well-known for his Oswald the Lucky Rabbit cartoons (co-created with the great Ub Iwerks, of course). Now in celebration of Oswald’s 90th birthday Animation Scoop let us know about a new hardcover book dedicated to his legacy. Oswald the Lucky Rabbit: The Search for the Lost Disney Cartoons (whew!) is coming out this week from Disney Editions. From editor David Bossert’s press release: “For the first time ever, all the known material and information relevant to Oswald the Lucky Rabbit has been aggregated into one book, including never-before-seen images, photographs, development art, production artwork, scripts, as well as gag and situation notes are all inclusive. This handsome volume contains a variety of color posters, many of which were found at auction houses and with collectors. This deluxe hardcover edition features an embossed cloth spine and is profusely illustrated with many rare images that reconstruct many of the still lost cartoons in the series.”
