Rafael D. Palacios (1905-1993) was a prolific and highly successful free-lance artist and illustrator specializing in book jackets and maps for major U.S. publishers in the mid- and late 20th century. Among his notable maps are those in most of Isaac Asimov's history books and in Bruce Catton's Civil War books.
Beginning in 1938 Palacios worked for American newspapers as an illustrator and translator of comic strips. In the mid-1940s, he shared a studio with several other freelance artists and did a number of covers and endpapers for Bantam Books. His endpapers had a strong cartographic quality and served a similar purpose with Dell Books' mapbacks.
