I am a collector of salt & peppers and there are some
very good books out there. There is : The Complete
Salt and Pepper Shaker Book by Mike Schneider. It is
really good for pictures. Also, The Collector's Encyclopedia
of Salt & Pepper Shakers second series by Melva
Davern. Also Helene Guarnaccia has four or five books
out. I have over 1500 sets of Salt & Peppers at this point.
Good Luck in you search. Also if anyone would like to
e-mail me to talk S&P please do. Thank You.
