Following its acclaimed predecessors Tal Uf Tal Ab (2010) and You Would (2012), Park / Sleep is the third in the series of Robert Frank's late visual diaries. It takes up his familiar collage technique, combining new and old snapshots mainly of Frank's friends, family, and home/studio, but also scenic and urban settings and interiors. The images are accompanied by short texts-notes, pieces of conversations, poems, and thoughts.
