Since i truly *love* the book, i am sorry to admit that i am not that enthusiastic in this poster. It does not bring anything new (... ok, probably it is not supposed to do that at all), but even does not sum up the hooks that exactly. It is something like a simplified patterns catalogue with different kinds of singular representations, that you already know from the book. So i guess a person who did not read it would never gain any use from it. The lower half of it is not of any use at all even for me... and at last it is not very beautiful.
I suggest to layout your own patterns poster which would probably even rise your skills. Or probably it is an even better idea to just stick something totally different, but more beautiful on the walls of your office. Buy the book, anyways.
