Art Nouveau and Art Deco Jewelry: An Identification and Value Guide

This shows some beautiful pieces in it, but the organization of the books leaves a lot to be desired.
It has as follows: colour plates with descriptions (which lack the maker's names); lists of motifs and materials; list of designers (without showing the makers' marks); glossary of terms.
It would have been much more efficient to have the designers' names, showing the designer marks within the description accompanying the colour plates.

Small, but lots of photos. Good overview for a beginner, but not adequate for someone who really wants to go in depth.
