"When I was a kid, I purchased a ditto machine, a Spirit Duplicator, and started printing my own comics like Crimestopper Monthly and Vampire Kiss— sold them through Rocket's Blast, a fanzine. Steve Ditko, the Spider-Man artist, even drew a cover for me. I had two fan letters published in Spider-Man #11 and Adventure Comics. I'd write letters to artists. Ditko and Joe Kubert| Kubert wrote back to encourage me."
"I went up to Marvel around lunchtime and spotted Stan Lee coming out of Marvel’s building. I introduced myself and told him I just got out of the service and asked if I could show him my portfolio. He said he was going to lunch but that I could go up to Marvel and say that Stan said I could show my work to John Romita, the art director. I was able to go in right away to see him."
