The aim of this book is to present in color, identifiable and collectible art glas produced during the latter part of the 19th and first part of the 20th century. Most of the glas illustrated was individually hand made, no two shapes or colors being absolutely identical. However a few categories of blown molded glass produced in the same period are included. (Key Words: Art Glass, Collectibles, Vases, Ray Grover, Lee Grover, Louis Comfort Tiffany).
