The cover is dedicated to the pencil: a common and simple object, within everyone’s reach. For that reason it goes unseen, but it has its own unexpected beauty and it is the bearer of a social and cultural history. Between the pages of INVENTARIO 15 we find the sections that arrange its contents in a flow of thoughts, objects and images. In “Bounces” Beppe Finessi explores the meanings of the relationship between “full” and “void”, “visible” and “invisible”, while in “Judicious Pairings” Stefania Di Maria collects works that share the theme of “NO”. “Personal Inventory” presents an original design manual through the work of Corrado Levi. In turn, Corrado Levi shows Lina Bo Bardi’s “Seduta da bordo strada”, created in 1967, through his own “Why”. Manolo De Giorgi’s section “Hues”, after talking about orange and green in recent issues, this time focuses on works, objects and spaces marked by the colour brown. Paolo Bocchi’s “Normal Wonders”, with drawings by Marco Manini, transforms everyday objects into “poetic anonymities”. For “Myths of Today” Francesca Picchi chooses James Irvine, retracing the stages of his work as a designer, while Giulio Iacchetti’s “Short Notes” are dedicated to the pipe. In “Lessons”, Alberto Meda talks about his concept of industrial design through some of the projects developed during his career. The protagonist of “Temporalia” by Elisa Testori is tape: a material dear to contemporary artists. Finally, Roberta Valtorta’s “Other Gazes” is dedicated to carousels and their evocative power, combining travel, games and dreams. The pictures that open and close issue n. 15 of Inventario are by Valentina Sommariva who interpreted the lamp Buds by Rodolfo Dordoni and Satellight by Eugenie Quittlet.
