This paper documents the drawings, installations, video works, and performances that were produced as part of Bryan McCormack's "Yesterday/Today/Tomorrow" ("Traceability is Credibility") conceptual work at the 2017 Venice Biennale in collaboration with Henry Bell and undergraduate students at Sheffield Hallam University. It also includes two videos: the first of which was part of McCormack's installation, and illustrates the application of performance methods inspired by Augusto Boal's Image Theatre techniques. The second video gives a brief impression of how these methods functioned in a live performance in Venice in May 2017.
