Book excerpt: In Portrait of a Young Painter, the distinguished historian Mary Kay Vaughan adopts a biographical approach to understanding the culture surrounding the Mexico City youth rebellion of the 1960s. Her chronicle of the life of painter Pepe Zúñiga counters a literature that portrays post-1940 Mexican history as a series of uprisings against state repression, injustice, and social neglect that culminated in the student protests of 1968. Rendering Zúñiga's coming of age on the margins of formal politics, Vaughan depicts midcentury Mexico City as a culture of growing prosperity, state largesse, and a vibrant, transnationally-informed public life that produced a multifaceted youth movement brimming with creativity and criticism of convention. In an analysis encompassing the mass media, schools, politics, family, sexuality, neighborhoods, and friendships, she subtly invokes theories of discourse, phenomenology, and affect to examine the formation of Zúñiga's persona in the decades leading up to 1968. By discussing the influences that shaped his worldview, she historicizes the process of subject formation and shows how doing so offers new perspectives on the events of 1968.
