I guess I feel qualified to reply - the book you have is totally new from start to finish (although it is the same long saga of course!!). The first book told the story up to 1983-ish while 'The Real Thing' is essentially the same book with a few new pics and a chapter added to take the story to 1993-ish.
For the latest book, I started over and only kept about 20 or so photos - out of the 300 - as I thought they were important enough to warrant using again (or - not leaving out). So you are safe buying either or both. Happy hunting.
