I was very lucky to snag this one!
According to Roger and Caroline (who were kind enough to answer my email) - this one is a true rarity or possibly even unique and there wouldn't be that many double-signed GD & RWS books out there at all.
As you can probably tell, i am very excited to own it!
Will never part with this (well, maybe reluctantly trade for a very special watch or something else special indeed down the line).
Enjoy your weekend
