This week we’re talking with Chad Sell, creator of the Eisner-nominated graphic novel “Cardboard Kingdom,” about a group of neighborhood kids who build an entire make-believe empire over the course of a summer. Chad’s got another graphic novel due out next year, “Doodleville,” plus a “Cardboard Kingdom” sequel in 2021. We talk about his work, his “Ru Paul’s Drag Race” fandom and how early Image Comics can warp a young mind.
