I found this image a long time ago. I don't remember the name of the artist, but it is a custom depiction of the satellite-era Justice League in the Bruce Timm style of the Animated Universe.
Then, not too long ago I realized that the above image is an homage to the last page from Justice League of America #200 by George Perez.

Note that the DCAU-style version up top corrects the one major flaw of Perez's drawing by including Hawkgirl among the other heroes.
