Appreciate, then you can (Part 56)....

 Perez Appreciation Post

 Back in the mid-80's The Maestro George Perez drew, and co-wrote, DC Comics' Crisis On Infinite Earths miniseries.  This is the cover of, I think, issue #7.   In this issue, the super-villains attack, as the cover illustrates. 

There's bad guys from Earth-1, Earth-2, Earth-2, Earth-C and perhaps others. 

I'm not gonna try to name them in any kind of order, but I see Dr. Sivana, Cheetah, Copperhead, Sinestro The Joker, Lex Luthor, Deathstroke, Gorilla Grodd, Mirror Master, Clock King, Poison Ivy, Soloman Grundy, Icicle, Captain Cold, Eclipso, Punch & Jewelie, Kobra, Chemo, Enchantress, Validus, Brainiac, Penguin, Dr. Polaris, Killer Frost, Star Sapphire, Starro the Conqueror, Black Adam, Trickster, Silver Swan, Captain Nazi, and Blockbuster, among others.

But seriously, look at the detail and all the characters and such.  Wow...truly a Maestro.
