Headcanon: Steve Rogers is a fan of the Wonder Woman comics
Headcanon: As DC is fiction within the MCU, Steve is a fan of Wonder Woman comics since the December 1941 debut. A fiercely independent brunette woman who fancies an American intelligence officer named Steve: it is the stuff of impossible fantasy.
While on the USO tour, he writes and begins to draw a whole fan series inspired by Peggy Carter’s struggles. He pitches an idea to have a Wonder Woman USO show, even tries out a dress rehearsal like here: http://seedoidraw.tumblr.com/post/108264680934/uso-show-1942 but the show handlers reject it
Upon defrosting, Steve is invited to Comic-Con as an author because his Wonder Woman series in his sketchbook was rediscovered in 1998 and published, becoming the most popular modern run.
