In which comic did superman actually fight with superman from Earth 2?

I saw a scan of Superman exchanging punches with super man from earth 2, I don't remember that happening in issue 5 or 6. So is there another tie-in or something that expanded the fight?

Do you mean their fight in Infinite Crisis? I know it happened in the main series, but it also may have happened in a tie-in. The Superboy Prime with the Titans is expanded in the TT tie-in.

This?

@mysticmedivh:

Huh. Is that Kingdom Come Superman vs. TDKR Superman in the back?

This one

@jedixman:

Honestly ... I can't tell.

That could be any Superman for all I know.
