One of the main focuses of the Museo Nacional Centro de Arte Reina Sofía Collection is to present recent acquisitions to the public. Under the policy of exhibiting and rotating the Collection as much as possible, there is the addition of the new presentation of Opera by Öyvind Fahlström, produced in 1952-53 and the first significant work by the artist. As a result, an exhibition room has been designed for the sole purpose of exhibiting the piece, highlighting its theatrical nature and relationship with musical language.
For the purposes of the Playgrounds Exhibition, three works by Ángel Ferrant have been loaned to the Museo, corresponding to the set of wooden children's toys he produced for the Caño Roto Housing Development (1957-63). According to Antonio Vázquez de Castro, one of the architects in the aforementioned project, Ángel Ferrant took an interest in the experience of the housing developments and wanted to "make a generous contribution, charging what a carpenter or locksmith charges me" in designing these games.
