Andries Copier (1901-1991) is the greatest glass artist the Netherlands has ever known. During the extended period that he was associated with the Leerdam glassworks, he put the 'Leerdam' name on the international map. His Gilde service belongs to the canon of Dutch design. His one-off art pieces are world-famous and his ability to produce original and attractive designs for an affordable price has fundamentally influenced the development of industrial design in glass. This substantial publication catalogues almost 2,000 works, all the works produced in series, and boasts more than 1,200 illustrations in colour. It marks the culmination of the Copier Research Project.
