What's the oldest book you own ?

[Badger]

The Bible?

This. Beyond that, a 1959 reprint of The Great Game of Politics originally published in 1923. A brilliant insiders guide to the world of ward politics.

As an original printing, a 1934 book on The Conquest of Mexico. Rather predictable apologism for Cortes (even though the Aztecs sucked in the early 16th Century).
