All Aboard! has been with me since my early teens. Living in Kansas in the 1980's there was very little Lionel around, and, obviously, no internet. I was 12 or 13 when I purchased the book, and it was the first time I saw Lionel catalog art and discovered the Lionel story. I've read and re-read the book over the years, and it still makes me happy to think about those memories.
As posted above, it was what got me seriously into O-gauge trains, and has been with me all these years. Because of this topic, I just pulled the book out and skimmed over it again. Absolutely the best book about O-gauge, and possibly all model trains, ever written.
