Juan Rulfo was "The Writer" in Mexico in the sixties and seventies, he is been translated to 52 languages. One of the most characteristic things of his work is that he published a novel, a collection of short stories and two screenplays, that's all. Recently the heirs of his copyrights, aka his sons, decided to publish "everything" he did, that includes almost a thousand of his 6x6 negatives he took out of a Rolleiflex camera in his travels around the country.
My personal opinion is, he was the greatest of the authors of the "magic realism" writers in spanish, if the comparation is valid, the William Faulkner of Latin America. His photographic work is great, but the books and the prints you can see is product of the great job of what curators, editors and heirs did trying to convert a great writer in a good photographer. Anyway, you can see his genius in his photos, but he made it a lot better in literature.
