Don't know the artist, perhaps that's his name vertically on the left hand bar.  But any way, it shows some members of Earth-2's JSA, from the late 70s to early 80s. 

Clockwise from upper left: Huntress, Green Lantern, Hawkman, Power Girl, Hourman, The Flash, Robin

Green Lantern, Batman, Aquaman, Wonder Woman, the Flash.
