In 1968 he represented Mexico in Salón Codex de Pintura Latinoamericana de Buenos Aires , where he won the prize " Premio Femirama de pintura . " 1968 , a crucial year in global politics , is also fundamental in Mexican history : a week before the inauguration of the Olympic Games in Mexico City , the military suppressed a student demonstration ; hundreds of participants died . Impressed by the situation and in danger of being imprisoned , Ehrenberg went into exile to England with his family . It was there , with David Mayor and Martha Hellion , that the Beau Geste Press was founded , a collective of artists dedicated to publishing the work of visual poets , conceptual artists , neo-dadaists and experimental artists , many of whom were connected to the Fluxus movement . During these years Ehrenberg formed part of the foundation of the group " Polygonal Workshop , " where he won the Perpetua Prize for the design and illustration of Opal Nation 's " The Man Who Entered Pictures , 1974 , " edited by Southwestern Arts Association/British Arts Council
