From early in 1968, a truly iconic Silver Age DC horror cover: House of Mystery #174.
It was penciled by Carmine Infantino who would go on to become DC's editor in chief. The name of whoever inked and colored it is lost to time but if I had to guess I would say Joe Orlando.
My 9 year old self was absolutely mesmerized by that art. The arched doorway, the ornate knocker, the pale, ghastly hand with the long gnarled fingers beckoning the children to enter, the evil, glowing eyes. I had to have that comic. Mom said, "No, you'll get scared and then you'll be up all night." "Please, please please!" I whined. She finally relented and bought it to shut me up.
So I read it and then I got scared and I was up all night. I wound up sleeping between Mom and Dad. But whadday gonna do? That cover was too good to resist.
A couple of years later the great Neal Adams did a variation of this cover for The Brave and The Bold:
Yep, Mom bought it, I read it, and I was up all night. Give me a break. Even Batman was afraid to enter The House of Mystery. This story was written and drawn by the Batman team supreme of Denny O'Neil and Neal Adams, the same two gents who created Ra's Al Ghul. And it came out on October 27th, 1970. Right before Halloween.
I love comics.
