I received the book a few days ago, which looks authentic. The images are high quality, with text overlayed on top of some of them, which would have been a pain to copy without seeing raster around some of the high-contrast edges.

The book also has small signs of wear, including tiny scratches on some of its pages, and some dents and worn edges on its soft-cover. There is a 1.5 inch dent on the back of the book, which wouldn't make me say the book is in mint condition as described.

However, for being a 23-year old book, it is in great condition. Its images are some of the most inspiring ones I have ever seen.
