I have searched a very long time for a such a book. My 10 year old has been into Legos for years, but loves to read about anything he's interested in as well. This book contains a timeline of Lego products that will surprise you, as well as Lego creations that are simply amazing. My son and I liked the book because it is very informative.It shows how Lego sculptures are created from start to finish, even including how many pieces each design took. The pages are all full color and is set up a style similar to the newer picture encyclopedias, which my son liked because they placed information all over the page.Overall, this is a great investment, the book is really well constructed, it is full of information, and it will get looked at over and over. I would recommend it for any child with more than a passing interest in Legos, but I was surprised at how much I enjoyed all the information in the book, so adults would really enjoy it too. I found this to be a no regret purchase.
