Just got a reply from Marc Heiremans. Wayne is spot on about this.
Good morning Mr Thomas,
This book was erroneously and prematurely announced by my publisher, many years ago. In fact, it has never been released.
It is now definately schedueled for 2013, at the occasion of a travelling exhibition of "Seguso Vetri D'Arte", held at the "Museo del vetro" in Murano, Italy, at the "Neue Sammlung" museum in Munich, Germany, and at the "Design museum" Ghent, Belgium.
Best regards, Marc Heiremans.
