After many years of repression and silence, popular movements arose during the 60s and 70s, which established the basis for a social and cultural net and contributed to the settling and reconfiguring of the Basque cultural community. This paper offers an approach to that particular sociocultural context by analysing the first artist?s book to be ever published in Basque: Isturitzetik Tolosan barru (Itxaropena, 1969), by JosAnton Artze. In order to understand the context in which that book of poems emerged and its contribution to experimental poetry, this paper presents the collective and participatory dynamics which led the book?s appearance and analyses the ways in which experimentation materializes throughout it. In this context, the poems are analyzed textually and contextually, focusing on its sonorous, visual and architectural dimension. Finally, the conclusions reflect on the position that this poetic work has acquired in Basque literary historiography.
