In March 2019, Luis Fernández-Galiano gave a series of lectures at the Fundación March that intended to condense the culture of the 20th century in four episodes with four cities as protagonists: a series that gathered large audiences and since continues having a remarkable number of viewings online. In an effort to capture them on paper without losing the oral freshness or the graphic profusion of slides, the new issue of AV revisits golden Vienna, interwar Paris, Cold War New York, and the Los Angeles of Hollywood and Disney to take stock of the flourishing of cities that attracted the best talent of their time.
