This morning, on the first day of New York Comic-Con 2014, DC Co-Publishers Jim Lee and Dan DiDio came together with Chief Information Officer and Executive Vice President of USPS Jim Cochrane and USPS Art Director Greg Breeding to formally launch the new Batman line of Forever Stamps in commemoration of the superhero’s 75th anniversary. The stamps represent four distinct eras in the Caped Crusader’s history– the Golden Age, Silver Age, Bronze Age, and Modern Age. Though the event was closed off to the public and available exclusively to press outlets, you can check out the entire ceremony (which also includes a special guest appearance!) in the YouTube playlist above. If you’re not the video type, or you don’t have headphones on you at the moment and don’t want to pump up the volume, you can also look through our photo coverage of the event in the gallery below (which includes a special look at a limited edition framed first issue set of the stamps)
