Happy Birthday, Cosmic Boy!

According to the 1976 DC Calendar, today will be the birthday of Rokk Krinn, better known throughout the galaxy as Cosmic Boy.
Cosmic Boy as one of the founders of the Legion of Super-Heroes and as its first Leader is considered Legionnaire #1! He served with distinction for nearly fourteen years until he retired to act as Senior Advisor.
Cosmic Boy is an Aquarius. He shouldn't let his emotions distort his experience. He's better off to take a cool-headed approach to relationships.

As an extra bonus, here's a scene where Cosmic Boy hangs out with his girl-friend, Night Girl, seemingly *not* taking the horoscope's advise.  (Superboy/Legion of Super-Heroes #212 with art by Mike Grell)
