There has never been a normal superhero wedding.
This is from Doom Patrol # 104, 1966 with the wedding of Elasti-Girl and Mento, along with an attack by the Brotherhood of Evil we are treated to some of the oddest renditions of other DC characters, I mean was the Tina Fay of Earth 1 standing in for Wonder Woman? Are those the pre-teen Titans? And Super-Hip?!?
