As the title says, it's a poster book featuring selected covers from various Wolverine titles through the years, drawn by some of the best comic book artists in the business. There are 36 posters all in all; the credits are found in the inside front cover. The posters are only as good as the scan quality, however, and fortunately this is a high-quality 1280 px DCP scan. The unretouched cover featured above is a good example.
