 Dear Friend and Colleague:
I congratulate you and Gallimard on the publication of Quetzalcotal et Guadalupe, an important event in the history of Latin American studies, and I look forward to the difficult yet pleassant task of translating it. I belive that our Press Director, Mr. Richard Congdon, has already written Galllimard to say that he wishes to take up the option to publish the work in an English translation. Â (…)
Cordially,
Benjamin Keen
Professor.
