This stunning, substantial volume documents William Frej's forty-five year search for remote Maya sites primarily in Guatemala and Mexico, inspired in large part by his discovery of the work of German-Austrian explorer Teobert Maler, who photographed them in the late nineteenth and early twentieth centuries. Many of Frej's magnificent photographs are juxtaposed here with historic photographs taken by Maler, and reveal the changes in the landscape that have occurred in the intervening century.
