Portable Monuments continues the artists' preoccupation with Brecht's remarkable 1955 publication War Primer. Using a series of coloured blocks as a lexicon, Broomberg & Chanarin have developed a code that - like Brecht's poems - has become a methodology for interrogating and deconstructing photographic press images. Their code has evolved through a series of workshops and is designed to function as a pedagogic tool. Each workshop is a collaborative effort to refine the code. The assemblages shown here are the results of these debates.
