The series was told
across three large prestige format comic books. It mixes alternate versions of
DC super-heroes with alternate-reality versions of real political figures such
as Joseph Stalin and John F. Kennedy.
In Red Son, Superman's rocket ship lands on a Ukrainian collective farm rather
than in Kansas, an implied reason being a small time difference (a handful of
hours) from the original timeline, meaning Earth's rotation placed the Ukraine
in the ship's path instead of Kansas. Instead of fighting for "... truth,
justice, and the American Way," Superman is described in Soviet radio
broadcasts "... as the Champion of the common worker who fights a
never-ending battle for Stalin, socialism, and the international expansion of
the Warsaw Pact."
His "secret identity" (i.e. the name his adoptive parents gave him)
is a state secret.
The series is split into three parts and spans roughly 1950 - 2000. (Source: Wikipedia)
