 The Silver Age Krypton made a rare Post-"Crisis" appearance in "The Sandman" #48, during a flashback sequence.Following "Crisis on Infinite Earths", which rebooted the history of the DC Universe and retroactively eliminated the existence of the Golden and Silver Age versions of Krypton, writer/artist John Byrne was given the task of recreating the entire "Superman" mythos.This rewrite was started in the 1986 "Man of Steel" miniseries, which addressed Krypton in both its opening and closing chapters.
