Justice League of America - Extended Version

As so many people asked for an early 1980s JLA with Martian Manhunter (though he hasn't been present at that time) and Phantom Stranger (though his membership never was really clear): 
HERE THEY ARE! :-)
Dedicated to one of my favourite artists of that time: Dick Dillin!
(His and Joe Staton's work are still inspiring and driving me the most)

Justice League Of America

The Justice League of the satellite era from 1980.
(After Firestorm joined and before Zatannas costume change. Martian Manhunter has not been present at that time as a member. It can be discussed, whether Phantom Stranger should be added or not ;-))
