In 1977, Rico, Sergio Aragones, and television and comic-book writer Mark Evanier co-founded the Comic Art Professional Society (CAPS). Rico also worked with Aragones as scripter for the artist-plotter's female-detective strip "T.C. Mars" in Joe Kubert's magazine "Sojourn". Also in 1977, Rico drew a six-page chapter starring Captain America in the World War II-superhero flashback series "The Invaders Annual" #1. In 1979, Rico drew the cover and wrote an introduction for a 128-page anthology of black-and-white reprints, "The Magnificent Superheroes of Comics" [sic] "Golden Age" #1 (Vintage Features).
