This book pays tribute to two important systems of architectural representation: the model and the photography. It rescues over one hundred original photographs of outstanding models - finally built or not built - in Spain during the twentieth-century. A modern, visual, critical and historiographical discourse of the first magnitude. Beyond the analysis of their technical or compositional structure, the book includes sample pictures by photographs like Catala- Roca, Kindel , Pando, Llado, Maspons - Ubina Gomez or Massats and architects as Aizpurua , de la Sota and Higueras
