A book that the late physicist Stephen Hawking signed in 1973, back when he was still able to hold a pen and scrawl out his autograph, is hitting the auction blocks.

Hawking, along with several of his colleagues, signed the book as a parting gift to one of their co-workers who was leaving his job as a computer operator at the Institute of Astronomy (IOA) at the University of Cambridge, in England.
