Searching for the lost, but once published stories of Dr. Seuss, Charles Cohen unearthed a slew of magazine covers that Ted Geisel had created back in the 1920’s.
With some sleuth-style hunting, he found old magazines containing these stories and after some online posting, an associate publisher/VP at Random House, who had formerly been the art director for Geisel’s last books, snatched up the magazines. That was back in 2004, a hunt that laid the groundwork for The Bippolo Seed and Other Lost Stories.
