This site and a related Delphi Forum are reporting that a sheet of DC superhero stamps will be available in 2006, with a Marvel sheet due in '07. I had a hard time understanding the e-mails I was sent this morning on the subject, and couldn't really follow a citation route from the site that's saying this, so who the heck knows? Me, I'm a big fan of the Robert Penn Warren stamps. Everyone should All The King's Men. It's beautifully written (Warren was a poet; it shows), and I thought the book was about 25 times better than a lot of books from that era with similar reputations.
