Disney Masters Volume 402: Romano Scarpa and Joe Torcivia: Captain Retro Duck Retros Again is an in-universe book published by Fantagraphics at some point prior to Spring of 2020.
Description[]
This entry in the Disney Masters series is a hardcover reprint of some of the adventures of comic-book superhero Captain Retro Duck, beloved of Donald Duck; to his outrage, Joe Torcivia, one of the comics' authors, hadn't been contacted about the book, let alone commissioned to write a foreword. At any rate, in April of 2020, a serene Donald read through the purple-covered book when forced to stay at home.
Behind the scenes[]
