It is hard to ascertain what the real purpose of the book is, beyond collecting some fees from the brands featured. The book offers a two page introduction, which is relatively sensible, if basic, followed by two page entries on a selection of brands - chosen, it seems, according to who would pay, rather than what brand is strongest / most interesting.
The two page entries are mostly dominated by a single large advertisement shot and have a description about some feature of a brand next to them. The descriptions are a bit random and will hardly provide readers with more but the most superficial knowledge - anyone who has spent at least a year in Western Europe / US in the last two decades can hardly not know the brands to the depth presented in this advertorial.
In a sense it could be used as a coffee table book(let) but as opposed to the Taschen volumes in the same category it has neither the focus, nor has it had a careful editor, who has selected the brands / advertisements according to a sound, or even interesting principle.
