Foregrounding exhibition architecture and design as the framework for looking, Models, Open Letters, Prototypes, Supplements presents a group of recent photographs within various mobile wall and exhibition systems, whose materials and designs have been collected from Williams’ recent exhibitions history, as well as supplementary material displayed in vitrines produced in 1975 by Leone Pancaldi, one of the driving forces behind the renewal of the modern Italian museum architecture. Williams explores aspects of realism traditionally associated with photography through the visual and aesthetic conventions that shape how we perceive our world. Family and society, cutaway and cross-section, object and function, ideology and immaterial labour, and time and duration are revealed as structures and models of representational systems, thus activating a progressive process of disclosure that aims at finding, for each individual element, the traces of their own representation.
