Has anyone seen or bought this? http://thebrickblogger.com/2012/08/unofficial-lego-collectors-guide-now-available/ For $30 or

Gary has actually reached out to us and I will be posting a page like that here on Brickpicker. Its a ton of fantastic information for vintage sets. The amount of details is staggering especially for items where information is so scarce. It's not like today where there are press releases tons of images, etc. He has collected more than anyone in this area. Look for the page to appear here soon. We definitely appreciate and support the work he has done.

I have read the sample pages and they look to be very detailed. So I will probably be purchasing a copy soon. I bought the Lego Collectors Guide 2011 edition which is interesting but is only really a list.

....Woooow.... This is truly one heck of a collector's book. Like you said Jeff, the amount of info for such older items is rather staggering and awe inspiring. I relish these kinds of books. Always make excellent reading material!
