The spy who me loved...
This is such a pretty comic strip! Jerry Grandenetti, who was an assistant to Will Eisner, did an excellent art job on this episode of Señorita Rio. The sexy spy had a distinguished career as a lead in Fight Comics for a few years until displaced by Tiger Girl. Her adventures were drawn by top artists like Nick Viscardi (later known as Nick Cardy), Lily Renée, and Jack Kamen (if my art-spotting skills are correct with what copies of Fight Comics I've seen).
There's a recap of Rio's origin in the splash panel. This is from Fight Comics #65, 1949.
