Re/Trace-Formations of Likeness is The Walther Collection's first extensive publication to juxtapose photographs from diverse cultures, time periods and materialities, following its 15-year exhibition and publication program. This book includes portraiture, documentary and conceptual photographs by leading artists, together with vernacular and archival images. Interweaving a multitude of artistic positions from Africa, the Americas, Europe, Japan and China, it presents a global dialogue on the diverse paths of development taken by historical and contemporary image production. Drawing on photographic and video works from the extensive holdings of The Walther Collection, Re/Trace focuses on portraiture and the body, exposing the social, cultural and political constructions that shape not only our representations but also our identities and experiences. Exploring the featured works and concepts, Re/Trace presents new essays by Phillip Prodger, Steven Kasher, Natasha Bissonauth and Emmanuel Iduma, as well as previously published texts by Okwui Enwezor, Corinne Diserens, Tamar Garb, Brian Wallis, Daniela Yvonne Baumann, Joshua Chuang, Oluremi C. Onabanjo, Christopher Phillips and Simon Njami.
