wow, I got a book printed in 1790, you got me beat!
It is a memorial to Samuel Davies.
I love the paper in those, it is a far better stock than the paper of the early 1900s, and helps you date a book when you pick it up.
I found a dictionary ca. 1814 at a rummage sale in fairly rough shape--boards loose, end paper missing, but almost all there. I would not have given it much more than a quick glance if I hadn't noticed the paper.
The perspective gained by reading the definitions of English words then has given me some insight into the Constitution and the other writings of the day. Much has changed, and not all for the better.
