Someone recommended the book to me - I couldn't remember who - although they really needn't have. It was always a case of whether I could justify the outlay. Then I saw it new on eBay for over 40% off and went for it. It's huge! And beautifully presented in a sturdy slip case.
I have the blue stickered 100 years hat as well. I couldn't get one at the circuit and had to wait until they did another run in August. I got them for myself and my son and his partner. Mine is behind me right now on my bookshelf - like your's, not destined to be worn.
