#earth-one

SUPERMAN (vol. 1) #301 (July, 1976). Cover by Jose Luis Garcia-Lopez, Bob Oskner and Bob Wiacek.

The Earth-Two Solomon Grundy somehow gets on Earth-One (I don't remember how; gimme a break, it's probably been 45 years since I read this issue) and promptly hands Superman's butt to him.

I was actually rather surprised by some of this. Finding out that Leo Dorfman wrote the Action Comics #363-365 "Leper from Krypton" arc, indicates he's actually been quite influential on Mark Waid, in my opinion. (And I definitely think that Cary Bates in particular influenced Grant Morrison. Bates' stuff ranges in quality a little, but the higher end stuff is fantastic.) I also didn't remember that it was Siegel who introduced Lena, and I was shocked to find out he co-wrote that mad Lex/Lois romance in earth-64.

Earth-One’s Dick Grayson had finally started going to college in 1969.  Neal Adams decided that Robin’s short pants-look was no longer appropriate, and in 1971 designed a new costume for the former Boy Wonder, which you can see in the foreground in the panel above.

The costume debuted in Justice League of America #92 (vol. 1), during one of the annual Justice League-Justice Society team-ups.  The Robins of Earth-One and Earth-Two got involved, and bonded over being treated like second class citizens by the older superheroes.  Then Earth-One Robin’s costume got trashed during a fight with the villain of the piece.  Luckily, his older counterpart had a new costume that a friend named “Neal Adams” had designed for him.  Earth-Two Robin gifted the new costume to his younger companion.

It was hoped that the new costume would become the official look for Earth-One′s Robin from that point forward.  The brass at DC, however, decided to stick with Robin’s original look, which he kept until he officially became Nightwing thirteen years later.
