At long last, all done! Can't tell you how many of those little puzzle pieces nearly got lost on the floor.
Observations from the Heroes of the DC Universe puzzle:
I've been thinking about it, and I believe we can imagine this "group shot," if you will, was taken just before the Genesis crossover. Consider Roy Harper in his pre-Red Arrow Arsenal suit; Lobo, the Spectre, and Hitman, who all had series at that time; and Artemis in her post-Wonder Woman #100 Requiem costume.
