These talking heads are all deceased now, but fortunately they were interviewed before it was too late for them to share their EC memories.
Wait, don’t go away yet! What about the other comic book companies that were publishing horror comics along with EC? This video features my dearly departed pal Joe Sinnott.
The earliest known surviving original art that Joe drew for Stan Lee is from a horror story. It’s page 1 of “The Terrible Trunk”, published in the Atlas pre-code comic book Adventures Into Weird Worlds #5, April 1952.

Thanks to comic art dealer Mike “Romitaman” Burkey, the page now belongs to Joe’s son Mark.
