The book that Paul mentioned is: Collectible Bohemian Glass 1880-1940, by Robert & Deborah Truitt, Published by B&D Glass, 1995.
As Paul said, there are many images of "Egermann line" items - they are reproductions in b&w of six pages from a Goldberg catalogue of the 1930s. Sadly, the images are too small to easily view details, but with patience and a magnifier, it is possible to get a general idea of the motifs used.
There was also a second book, published 1998, with basically the same title but for 1915-1945. It covers Art Deco and onward, but shows one "Egermann style" item from the Palda works and three from Exbor (the Exbor items are under a heading of "recent and continuing production).
