I found this lovely black leather covered notebook along with the other leather wallet/notebook just listed together at an antique shop in New Hampshire, and might guess they are somehow connected, but I don't know. This one was kept by a Robert White of Shelburn, Vermont, and while he left most of it empty--for someone to fill now--I love what is in it, including this diagram of The American Flag, with specifications! I also love that on the first page appears "Velocity of Sounds." "Elevations of some mountains," too, and a header suggesting he was planning to count the number of words in the Bible--but did not get that far!
6 3/8" x 4" closed. Pages measure 6 1/4" x 3 3/4". Just a handful of pages used, as documented, then about 40 unused leaves. Very good antique condition, sturdy and not a bit fragile, with light general wear and aging.
