A poster is wrapped around a small, square, vaguely low-fi book in which every page is scored by a red pattern of triangles, the expression of a personal golden ratio. This is the catalogue for Fraktur, a piece which also lends its title to the solo exhibition by Previdi that just closed at de Vleeshal, the former meat market in Middelburg, a triumphantly Gothic space that makes Portikus look like a Chipperfield-style white cube. And Fraktur is also a traditional Gothic script, like the Textura typeface that Gutenberg used for the Bible, the first massproduced catalogue printed in a spiky font that evokes architecture and the intersection of lines. History and style have shaped this book as well. (Don’t worry, though, the texts are clearly legible, in Garamond).
