User blog:The Multiple Men/Superman issue 164

This is the best single-issue Superman story we know.

Some of the good things in it include (SPOILERS AHEAD):

Superman knows he must accept Luthor's challenge (as he explains to Lois).

A battle of wits with formidable, alien weapons.

Luthor reprograms ancient irrigation equipment, on the fly, to drive pteridactyl-like birds from the natives' crops. The natives show him gratitude and acceptance, which gives Luthor pause.

On this parched world, Superman finds water, but only drinks what he needs, and leaves some for an alien animal.

Luthor, without admitting it, works with Superman to help the natives.

Superman flings icebergs from one planet to another.

Superman visits Lex in prison, and gives him a telescopic photo showing how the aliens have honored Luthor.

DC comics were pretty noble in those days.
