Hawkgirl is a new member of the new Justice League series by Scott Snyder, Jim Cheung, Jorge Jimenez and Mike Morales. And DC Comics are running tiered variant covers to help push subsequent issues of the series – whose first issue already sold a quarter of a million so they aren't doing too badly.
But the third issue will now have a new variant cover featuring pencil art by Jim Lee, featuring his portrait of Hawkgirl which will probably have the inked and coloured version as its variant cover, and is available based on retailers' orders of Justice League #3.
JUSTICE LEAGUE #3

John Stewart: Ultraviolet Lantern? Believe it! Under the influence of the Ultraviolet Spectrum, John Stewart engages in some ultraviolence against his teammates Flash, Wonder Woman and Aquaman. Meanwhile, the rest of the League investigates the scene of the fallen Source Wall fragment, and encounters not only a horde of giant monsters, but a pair of longtime archenemies using stolen Atom technology to literally get under their skin. Best to stock up on Cortizone for that sort of itch! All this and…the Turtle? Yep.In Shops: Jul 04, 2018
The issue in question will be sold on July 4th – or midnight on July 3rd in participating retailers.
And no, I don't know what it looks like. Maybe he hasn't drawn it yet? MAybe it will turn up on Twitch? Keep watching the skies – it is Hawkgirl after all. Here's a video of him drawing Hawkman while you wait.
