I'm glad I paid the extra money for this version. It is a larger book with great quality images and detailed illustrations. The book contains some essays for your interest/entertainment, but more importantly is the quality of the scans from the original manuscript. There are scans of the outside of the book from every angle. All of the fold out sections are there just like in the original with smaller images in the bottom corners to show how they fold out. I'm very pleased with this purchase. Don't buy a low quality reprint. If you want a copy of this manuscript for your collection then buy this version.
