In the mid-1960s, I'd spend the summers at my Grandmothers houses, splitting between Queens and a summer cottage out east on Long Island. Every year, when I'd come back, the kids in the neighborhood had changed. For example, one year everyone had Matchbox cars, and when I returned the next year with my greatly expanded collection, they had moved on to Hot Wheels and no one cared about my cars.
We'd play baseball or stickball in the mornings, but the afternoons were reserved for playing army, or star trek or super heroes. Sometimes we'd be the Legion of Super-Heroes, sometimes we would 'be the Justice League and sometimes we would be The Allies of Peace. The Allies were made up of just about any Marvel hero you wanted, so Thor could team with Spider-man and Iceman. I'd never heard the term before or since so it was just a long forgotten memory that would pop up every couple of years.
Thanks to the virus, I'm watching much more tv and a much wider assortment of shows. Today I'm binge-watching the 1966 Marvel Cartoons when an odd Submariner story comes on. Evidently, Marvel couldn't use the Fantastic Four so the animators chopped up the story of Reed and Sues wedding and eliminated all the FF characters and references. Instead of Dr. Doom leading an assault on the wedding, he leads an attack on the opening of Peace Plaza, where X-Men and other heroes are in The Allies of Peace. I believe this was the first and only appearance of the AOP.
