This volume investigates the cultural and social landscape of Spain through a synchronized, twenty-four-hour photographic documentation of the nation. The authors, David R. Cohen and Rick Smolan, orchestrated a massive collaborative effort involving dozens of professional photographers to capture a singular, comprehensive snapshot of Spanish life on May 7, 1987. By utilizing a wide-angle approach to geography and demographics, the book presents a mosaic of a country in the midst of post-Franco modernization and cultural transition.

The work serves as a significant archival document, providing a high-fidelity visual record of a specific moment in Spanish history. Its scope is broad and observational, offering researchers and enthusiasts a dense, multi-faceted perspective on the cultural climate of the era.
