I will post further information about this exhibition, which I visited recently,  as part of my formal review of an event for the module. However, in a nutshell, 'Van Doesburg and the International Avant Garde' at the Tate Modern is a must see for graphic designers/typographers and anyone interested in the links, crossovers and influences associated with the period exhibited including, Cubism,  de Stijl, Dadaism, Constructivism. The exhibition has been curated effectively in a chronological order so that it is easy to pick up on the development of influences that Van Doesburg relates to and involves himself with, from cubism, abstraction, through De Stijl into Dadaism and beyond.
