Grzegorz Gorny and Janusz Rosikon team up for another beautiful coffee-table book. This one teams with information and breathtaking photography on the Shrine of Our Lady of Guadalupe in Mexico City. What draws 20 million people a year from all over the world to this most visited pilgrimage center in the world? The answer, a 500-year-old piece of cloth depicting the image of Our Lady of Guadalupe, is found in Guadalupe Mysteries. Doug Keck of EWTN Bookmark interviews author and photographer on the mysteries they found, some of which have only been recently ‘de-coded’ by technological developments.
