"The Last Earth-Prime Story"
Quite an unusual day for the Man of Steel, a grumpy old man will not leave him alone. It even goes to the point that Superman must save his life when he attempts suicide. Finally Perry White deduces who this man is; Julius Schwartz. Except in this case the man in question may well be a comic-book editor from Earth-Prime, not the old media teacher whom Perry remembers.
Also includes a M.A.S.K. preview "Assault on Mount Mayhem"
which was included in every DC issue released in that month.
