Ger Apeldoorn shares a batch of early original gag cartoons by Mort Walker. Ger notices something about them:
"What amazes me the most when I look at these originals, is the fact that Mort Walker didn't use any white-out on them. I a quite convinced they are presentation pieces (since the editor okayed them on the front in red), but I still don't know if they were published."
Happy belated birthday, Ger -- and good luck with your quest!
