Antoni Muntadas' task consisted of intervening rather than exhibiting, of endowing the Pavilion with another dimension, of activating it in a different way. This book is the report of this intervention: the project introduces the invisibility of the archive through its olfactory presence: the archive, as well as all the documents about the project. The mediatic role of the Pavilion and knowledge of it through writings, the press and bibliography, which has reached so many people, led Muntadas to another type of olfactory proposal.
