Dave and I did a couple of Blackhawk stories together. I thought he did a fine job but Dave was never satisfied with anything he'd done. We were at some San Diego Con, coming back from lunch when an attendee pounced upon us — and "pounced" isn't a bad way to describe what this guy did. "I've been waiting to get you both to sign this," he exclaimed, thrusting an issue at us. I scribbled my name but Dave took a few minutes with his inscription. He signed the first page of the story and then he flipped to page four or five and drew something in the margin. I couldn't see exactly what it was but it looked like a hand. As we walked off, I asked him what it was he'd drawn.
He said, "I decided I drew Blackhawk's hand wrong in that panel so every time I sign a copy, I draw it right in the margin. I've done that about thirteen times now."
I said, "You can't fix 'em all, Dave. They printed 150,000 copies of that issue."
Dave grinned through that beard of his and said, "Okay, so I've got 149,987 to go." How do you not like a guy like that?
