This unique reference book compares the glass art of Samuel and Gottlob Mohn with the works of Anton Kothgasser. They explain the differences and similarities of decoration and painting using pieces from major museums and inaccessible private collections, and employing never-before published texts, images, and detail shots. Using the description of the glass as a starting point, the author recreates the time and lifestyle of its creation. Using his spectacular shots he points out what is important in the collection and describes vividly the important role played by the spirit of the piece when it comes to distinguishing an original from good copy. This bilingual book for the first time compares these cooperating but also competing artists and presents their individual characteristics. German and English text.
