Here’s a neat item that stretches the definition of “notebook,” or at least turns the clock back on it!

Brass and Ivory Pocket Notebook
It’s the 18th century version of the PDA. Beautifully crafted here in the US. Based on an original that Jefferson owned. These are made of sturdy brass stock with 4 old ivory pages and a pencil. Use this for making notes in the field and just erase with a wet finger when you are done. Folds up into a nice small package 1-1/8 inches by 4-1/2 inches by 3/16 inch thick. No batteries needed.

It’s $85 at Jas. Townsend & Son Ltd., “a mail order company that supplies 18th and 19th century reproductions for living history.”
