Nick Perks drew this Santa/Superman piece. So how this works is that every day until Christmas Eve, you can click on the current day's Advent Calendar post and it'll have a story in it that is part of my countdown of the 24 Greatest Superman Christmas Comics ever told! And I'll add links to the previous days in each new installment.
Here's Day 1, #24 on the countdown.
Here's Day 2, #23 on the countdown.
Here's Day 3, #22 on the countdown
Here's Day 4, #21 on the countdown
Here's Day 5, #20 on the countdown
Here's Day 6, #19 on the countdown
Here's Day 7, #18 on the countdown
Here's Day 8, #17 on the countdown
Here's Day 9, #16 on the countdown
And now for Day 10, #15 on the countdown is...
"War for Peace," from "Action Comics" #517 by Gerry Conway, Curt Swan and Dave Hunt.
In it, Superman breaks up a fight between some kids over religion...
He is then pulled into a fight between two alien races who are fighting over a shared religious artifact in a super subtle metaphor about religious disagreements. He solved things by destroying all of the weapons of the two races.
Simplistic stuff, but it worked well.
