This pioneering study presents an overview of the Mexican comic book industry, together with in-depth studies of the best selling Mexican comic books of the 1960s and 1970s. Most of the popular superhero, adventure, humor, romance, political, detective, and Western comic books are described and analyzed in detail, and then discussed in terms of how they reflect both Mexican and United States cultures. The study concludes with a critical discussion of the media imperialism hypothesis' applicability to the Mexican comic book.The comic book is Mexico's most popular print medium, read by all ages and socio-economic groups. Many may be surprised to learn that, in Mexico, Mexican comic books far outsell U.S. comic books in Spanish translation. The Mexican comic book is not a clone of its U.S. model, but rather a hybrid product that mixes U.S. forms and conventions with Mexican content. This work is a major contribution to the understanding of contemporary Mexican culture.
