Remember this from yesterday?

DC Comics posted it to their Source blog without any explanation, and I speculated that maybe it was one of those 75th anniversary variant covers they've been featuring. But why all the secrecy?

Turns out it isn't. Alex Segura explains on the Source that it's actually an Easter Egg that'll appear on the TV show Fringe tonight:

If you’re a fan of the show FRINGE on FOX, you know that part two of the show’s season finale airs tonight. And, as if you needed more reason to tune in (9:00-10:00 PM ET/PT) on FOX, we’ve got a few.

See, in tonight’s episode both universes are put at great risk as Walter (John Noble) and Olivia (Anna Tory) visit the “other side.” But what are some of the cool Easter egg-style things one would see on the “other side”? Well, stuff like that RED LANTERN/RED ARROW cover, for starters.

So tune in tonight, look out for more covers like the one above and come back to The Source tomorrow morning for a look at all the covers shown in the episode.

I don't watch Fringe, so I have no idea what he's talking about, but I'm gonna assume the "other side" is some sort of alternate version of reality where up is down, black is white and, um, green is red.
