Perhaps my least favorite cover on this run. You can barely see Supergirl and all those banners and logos at top take up way too much eye-grabbing space. Another messy Sekowsky/Oksner splash (sort of) several pages into the story. Noticeably more butt shots in this one, too, but drawn very unattractively.
Kirby had his Fourth World project taken away from him but his vast creativity immediately came up with this, another character that would be extremely influential at DC forever after.
The highlight of the issue--more Gray Morrow Vigilante!
Mike Barr, in later years one of my favorite comic book writers, pops up on this issue's letters page.
