Artist Joan Rabascall takes a deep dive into the postcard as a revolutionary form of mass communication in the late 19th century. Highlighting key milestones, like the birth of the tourist postcard. Rabascall also examines its impact on 20th-century experimental art practices.

The focus then shifts to a detailed exploration of the evolution of tourist postcards in Spain during the economic "opening" of the dictatorship, a time of significant change in both their content and design. Featuring postcards from Rabascall's personal collection, primarily from the 1960s to the 1980s, the book captures a pivotal era of growth tied to Spain’s booming sun-and-sand tourism. While it briefly addresses the postcard's survival in the digital age, the essay celebrates its golden years and enduring cultural relevance.
