The square format of this catalog raisonné reflects Kjaerholm's preoccupation with the square in furniture design. We were fortunate to have an extensive archive of photographs by Keld Helmer Petersen, who collaborated with Kjaerholm frequently. Because almost all the photos are Petersen's, the book has a distinct visual harmony. The black-and-white images, and the use of the modern typeface Futura, underscore the spare elegance of the furniture.
