Badly done. The information seems okay from what I know, but the execution of the book itself is horrible. The balance between text and illustrations, the quality of the illustrations that look like cheapo retro pop art (I know this is probably an artistic choice, but for that kind of book real picture would have been better), the quantity of those illustrations are also way too low and it just appear to me that it’s another case of bad mixed between the book edition/organization and the targeted audience!
