Let us know what you like about Geek by taking our survey. Back in the days of geek prehistory, a T-shirt was a signal to the world around you that you cared about your nerdy pursuits enough to fly them like a flag. Companies like Graphitti Designs contracted with movie studios and comics publishers to create shirts with our favorite characters and sold them up on the walls of comic book stores and through mail-order.The computer revolution has enabled the T-shirt world to become something totally new – affordable production and distribution means that shirts can be printed in small quantities and sold anywhere in the world. Starting with Threadless, dozens of companies popped up letting artists and designers show their stuff. It’s a better time than ever to be a geek fashionista, and if you’re looking to expand your wardrobe we’re going to help you out every week… on T-Shirt Tuesday.This week: DC’s flagship superhero team hits theaters, so you should come to the premiere in one of these Justice League shirts.Out Of The DarknessPlenty of ink has been spilled about how the DC cinematic universe is a lot darker and grittier a place than the Marvel one, for better or for worse. But there’s no denying that dousing those brightly colored costumes in inky black shadow can create some memorable visuals. This shirt design by k4k7uz takes the heroic arrangement from the Justice League poster and gives it an appealing chiaroscuro look.$20, buy it here.Pixel LeagueYes, there is probably going to be a tie-in video game for the Justice League movie, but it probably won’t be done in the quirky pixel art technique displayed here by viselner. DC isn’t quite ready to get weird with their flagship franchise, no matter how cool it would be. Oh well – you’ll always have this shirt which depicts the Trinity in low-res splendor.$20, buy it here.Justice League UnitedDC’s animated cartoons are widely agreed to be some of the best stuff they put out, so big ups to artist Grayson888 for copping the signature silhouetted heroes look from Justice League Unlimited and re-purposing it with the heroes from the upcoming movie instead. It’s a cool way to bridge the old and the new that works for fans of all stripes.$20, buy it here.The League Of JusticeThis one makes the list for the unique illustration style employed by artist jordanjamesb, who takes a blotchy line like Jae Lee or Frank Miller and a minimal color palette to create striking renditions of the group’s seven founding members. The DC characters are such icons they can be transformed and redesigned infinitely while still maintaining their power, and this shirt is a neat way to show that.$20, buy it here.Straight Out For JusticeThe cover for N.W.A.’s 1988 Straight Outta Compton remains one of the greatest pieces of album art ever, managing to be threatening even with thirty years of distance from the scene. This T-shirt by amodesigns replaces the L.A. rap crew with the core members of the Justice League, looking pretty gangsta as they give the DC Universe’s villains notice that the rap wars are here.$20, buy it here.Good Grief, Batman!It wouldn’t be T-Shirt Tuesday without at least one mash-up design. This illustration by RickThompson takes the good old Peanuts gang and assigns Justice League identities to them, with Charlie Brown as Batman getting his Bat-Kite stuck in the tree and the rest of the crew helping him get it out. It’s well-drawn, funny and sweet.$20, buy it here.Justice TotemWe like this design from Akiwa a lot – you might argue that it’s sort of culturally appropriative, but this is the same company that brought us Apache Chief so what can you say? Stacking the heads of the Justice League up in a totem pole helps cement their positions as the American monomyth, figures who are larger than life and outside of history.$20, buy it here.Heroes Of The LeagueI always loved the times when the Justice League wasn’t just the big guns of the DC universe but opened their doors up to unlikelier heroes – it brought them up to a new level and let readers see how they’d interact with truly planet-threatening villains. Artist casdavihay pays tribute to some lesser-known Leaguers like Booster Gold, the Question and Doctor Fate with this stylish shirt.$20, buy it here.Justice BeerThis shirt by halfabubble has us thinking – if each member of the Justice League was a frosty malt beverage, what would they be? Batman would probably be a midnight-black Imperial Stout that you can only handle in little sips, while the Flash would be a hoppy, mouth, stimulating IPA. We could talk about superhero beer equivalents all day, but this shirt sort of does the job for us.$20, buy it here.UniteWhile a bunch of the shirts on this list are sort of muted in design, this one from ShokXoneStudios is wild, exploding with color and style. Each member of the League either gets one of the letters in the word UNITE or the line on the top or the bottom, and there’s a ton of personality in each. It’s gleefully, unapologetically comic book style and we love it.$20, buy it here.JUSTICEHow the heck did designer The_Interceptor figure out that this concept would work? Sure, they pull a few strings to make the concept carry through, but the layout is impeccable, and it’s a striking design that will resonate with DC nerds who know that Vic Stone is Cyborg’s real name. Just a really clever take on a concept we’ve seen a few times around here.$20, buy it here.
