In the work carried out by Juan Navarro Baldeweg in the early years of his career, during his stay at the Center for Advanced Visual Studies (CAVS) of the Massachusetts Institute of Technology (MIT), between 1971 y 1975, it is possible to find out the principles that have guided his way of working throughout his life. In order to shed some light on his early work, the article presents the analysis of the collection of works, pieces and common objects shown in the studio that he occupied at the CAVS during those years. All of them are the record of his imaginary space, a mental realm of the artist in which the works are conceived and where the references and interests are collected. Thereby, his work studio is conceived as a passage, a transitional space between his imaginary or ideation space and the physical environment on which he creates his work, providing invaluable.
