Irma Boom founded an independent office in Amsterdam in 1991 and continued to work on projects in cultural and commercial sectors. A thorough reflection on a book's content leads Boom to her design decisions. It is her aim to enhance the reader's understanding while at the same time creating an object of beauty, with quality and permanence. One of Boom’s trademarks (Weaving as Metaphor) is the use of oversized type which successively shrinks from the opening to the end of a book as a way to lure people into reading the introductory pages. This book has a blank cover and alarmed publishers at the time but their unease presumably disappeared after the book's release, as it elevated Boom to international design stardom.
