All pictures are line drawings by the author.
Clear, Colored, Custard and Carnival by Marion T. Hartung. Out of print. The Encyclopedia of Duncan Glass by Gail Krause. Good reference book on Sanibel pattern and on some novelties. Good reference for picture identification if you collect ' stretch ' vaseline glass, but light on text and research.
