Rare book of the day – Signed Albert Einstein
A gorgeous, signed copy of Einstein’s canonical book, Relativity!
One of the more interesting books that passed through my wife and my hands when we owned a bookstore was a first edition of The Evolution of Physics by Albert Einstein and Leopold Infeld, signed by both authors on the ffep. That was probably one of the harder books we had to part with in our years running a bookstore, but with a new baby on the way, part with it we did.
