A complete 1958 Disneyland ticket book I found in a box

I found this in a box that my brother gave me and thought it looked fairly old. I was surprised to find out that it was a 1958 ticket book and the best part was, that it had not been used. I can not find another one like this book intact. It is also a courtesy guest ticket book and that is why it has an x at the front of the serial number I think. I have seen one 1958 kids book intact. I don't know how these courtesy books would have been sold or given out. I am curious to know more about it. I think that this is one of the Holy Grail of Disney ticket books, besides the 1955 ticket book. I would have put all the ride tickets so you could see them, but I could only put in four pictures. This was the last year before the E ticket came out in 1959.
