Superhero Anydays
This is by Jerry Ordway, and it shows a bunch of heroes featured prominently in the first several issues of the All-Star Squadron. This series took place on Earth-2 in the World War II era. Nominally, the All-Star Squadron was composed of all the superheroes in the USA at that time (by order of President Roosevelt), but in actuality, there was usually a core group of like 6, 8, 10 heroes at any one time.
In the air: Johnny Quick, Dr. Fate, Green Lantern, Firebrand II, Hawkgirl, Hawkman, Tarantula and the Shining Knight above them all.
On the ground: The Atom, Amazing Man, Robotman, Plastic Man, Liberty Belle, Steel, Guardian, Hourman

And today we also have two gender bent...well I don't think they're actually cosplayers, these look more like sexy Halloween costumes. But at any rate, it's Catwoman and Wonder Woman!
