The New Yorker is famous for its gorgeous illustrated covers, but the published covers are only the tip of the iceberg. Many, many cover proposals stay unpublished for various reasons.
Françoise Mouly, who has been chosing covers since 1993 as art director, authored a book giving these rejected covers some exposure. You can see some of these covers here, and see more as well as an interview on ImPrint Mag.
