This book has as its historical reference on the exhibition "Hegemonía y Visualidad" (Visuala, 1987), the artistic complement of the Simposio Gramsci held at the Instituto de Ciencias Alejandro Lipschutz (ICAL) in 1987, a seminar that called for a debate on the link between hegemony, art and politics and that brought together the left-wing idealists from that period. The book was published in commemoration of the 80 years of the death of Antonio Gramsci, and the thirty years of the symposium and its complementary exhibition. "Despite the scarce documentation that exists of both events and far from consolidating itself as a homogeneous or exempt of contradictions, the exhibition and the symposium have served as a pretext to raise a discussion around historiographic issues associated with the document in the field of art , as well as the forms of paratextual writing that were placed in the vortex between art and politics in the late eighties."

While INVENTARIO is "an inventory of textual categories that appeared among the texts discussed for the purpose of the study on "Hegemonía & visualidad (1983-2017)", which does not tries to be an index of key words, as they say, but a possible reading of the "Lapsus" -between failure and the farce- produced by the coexistence between politics and art, image and representation, within the framework of 1987 " (HKB Translation) --Page [9]. It includes the four video interviews to those who produced the theoretical debate in this exhibition. Such records constitute a historical document and the work around the voice of writers and critics who participated in this event, and of those who reproduced performative testimonies about their own historical account.
