Book dedicated to cellist and amateur photographer Guillermo Montesinos Pastor (Peru 1877-1925), a reference of the early 20th century Arequipeña photography. Unlike other of his contemporaries such as Max T. Vargas, Emilio Díaz, or the Vargas brothers; Montesinos was not linked to the commercial use of photography and resorted to it only to express his free and contemplative spirit in front of the Arequipa countryside, its volcanoes, its dazzling skies and clouds and its own home. The book edited and written by Dr. Andrés Garay, in co-authorship with Jorge Villacorta, is another chapter within a two-decade research carried out by the authors, with the aim of revaluing the great development of Arequipeña photography in the first decades of the 20th century and includes critical essays by plastic artist Blas Isasi, photo curator Cecilia Salgado and brothers Sebastian and Alfonso Montesinos Belón, sons of the photographer.
