From Hard Werken. One for All. Graphic Art and Design 1979–1994 by Ian Horton & Bettina Furnée (Amsterdam, Valiz 2018):
This cover was heavily criticised at the time for the playful and, in book-publishing terms, subversive manipulation of traditional letter forms, and for the use of metal foil which contemporaries felt was a particularly vulgar treatment for a literary work, reminiscent of trashy American fiction. In a newspaper article Hub. Hubben even suggested that Hadders, who he thought already deserved five years in prison for ‘damage done to the retina’ with previous designs, should now have his sentence increased by a year for the cover of De naam van de roos. And that for good measure Hadders should be muzzled. And that Hubben regrettably could not read the book, as he would not buy it for the cover.
The “traditional letter forms” here are of course Michelangelo by Hermann Zapf, while another Zapf typeface, Melior, is used for the publisher’s name.
