Schomburg is one of the defining illustrators of both the comic book and sci-fi golden ages, and you can see a partial list of his extensive work at ISFDB. You can see a list of the stories in this volume—the book’s subtitle is Stories About the Time When Men Will Be Adventuring to the Stars—here.

Love Schomburg’s art. I have a Captain Aero comic with a Schomburg cover from 1944.
