Green Lantern, Aquaman and many others. In 1963 writer Gardner Fox came up with a way to resurrect the super team from the 1940s known as the Justice Society of America. He made them residents of another Earth, vibrating at a different speed than the superheroes of the present day, the Justice League. Then he introduced a cross-over that would become a staple in the Justice League comics every year through the 1980s. I LOVED those team ups with all of those heroes.
Now, the first Four (two-part) stories of those team ups are collected in this full-color collection, and it brought back a lot of great memories. Of course I recommend it. It will always be in my comics library! - Rob
