At the first DC FanDome event, the cast of The Flash movie unveiled concept art featuring Ezra Miller's new flash costume. One piece of art featured Michael Keaton's Batman behind him --and now Design by Humans is selling that art on t-shirts.

There are several Flash shirts available to buy, most from the comic book. Two shirts, however, feature pieces of concept art from the event, both branded with the DC FanDome logo. Both the shirt with Michael Keaton's Batman and the one of just Ezra Miller's Flash are listed for $26.00.

Back in August, it was announced that Ben Affleck's Batman would join Michael Keaton's in The Flash, helping to portray the multiverse DC is so known for. Keaton first played Batman in Tim Burton's Batman, returning for the role in Batman Returns. When The Flash releases in 2021, it will be 29 years since Keaton last donned the cowl.

Ben Affleck first suited up as the Dark Knight in Zack Snyder's 2016 film, Batman v Superman: Dawn of Justice. He put the suit on once more for 2018's Justice League. Affleck will reprise his role two more times, first in Zack Snyder's Justice League and later on in Andy Muschietti's The Flash for a cameo. DC already confirmed that Affleck's Batman returning wouldn't have any impact on Matt Reeves' upcoming Dark Knight film, The Batman.

As Affleck vacates the role, Robert Pattinson will take over as the new Caped Crusader in the aforementioned The Batman. Reeves' film will show a younger Bruce Wayne than Affleck's did, depicting the crimefighter's early years in Gotham City.

An earlier report from Vanity Fair suggested that Keaton and Affleck's Batmen wouldn't be the only familiar-faced heroes returning. It also claimed that Keaton's Batman plays a major role in the movie. According to the report, "Affleck won't be the only Batman making a comeback; a few more of the alternate-dimension heroes who turn up in the Flash movie will be figures we've seen before. Michael Keaton's Batman from the 1989 Tim Burton film is also set to appear in what Muschietti said was a 'substantial' part."

Directed by Andy Muschietti with a script by Christina Hodson, The Flash stars Ezra Miller as Barry Allen. The film arrives in theaters June 3, 2022.

The shirts from Design By Human are now available for purchase.
