Book excerpt: The image of the shadow in midtwentiethcentury America appeared across a variety of genres and media including poetry, pulp fiction, photography, and film. Drawing on an extensive framework that ranges from Cold War cultural histories to theorizations of psychoanalysis and the Gothic, Erik Mortenson argues that shadow imagery in 1950s and 1960s American culture not only reflected the anxiety and ambiguity of the times but also offered an imaginative space for artists to challenge the binary rhetoric associated with the Cold War. From comics to movies, Beats to bombs, Ambiguous Borderlands provides a novel understanding of the Cold War cultural context through its analysis of the image of the shadow in midcentury media. Its interdisciplinary approach, ambitious subject matter, and diverse theoretical framing make it essential reading for anyone interested in American literary and popular culture during the midtwentieth century.
