Like I said about the Iwo Jima image a couple of weeks ago, if there's a classic image, it'll be updated, reworked and used time and again. Take the cover of Crisis on Infinite Earths #7, for example. The original had Superman holding Supergirl's broken body but it could just as easily be
Green Lantern Kyle Rayner holding Donna Troy . . . Black Adam holding Osiris . . .
Red Torpedo cradling Red Tornado . . . or some lunar mummy thing holding Seaguy.
It's so versatile!
