La Fortaleza Volante [The Flying Fortress]

A painting of a U.S. Army four-engined bomber seen from below fills the sheet under the Spanish title 'The Flying Fortress'. The tagline stacks virtue-and-power words ('pride', 'colossus', 'invincible master of space') over the aircraft, with no facts about missions or numbers.
