This was an one of the best comic crossovers ever! It was the very first time I was introduced to the Crime Syndicate and Per Degaton. This crossover followed on the heels of George Perez's sweet run on the Justice League of America and it doesn't disappoint.
I love this particular crossover because it ignores the whole time difference between the two Earths and just makes it a time travel multi-verse crossover...hell ya!
Plus the covers for this crossover rock. I have always had a fondness for this particular cover layout with a central picture being framed with floating heads on the side and bottom of each team, perfect.
