I am not certain why another person gave this a bad rating, stating that this was the worst 'ever'. The quality is suprisingly great! The B&W pictures are crisp and all the text in the book is fully OCR'd. The PDF has a sidebar with linked sections & TOC - its not a cheap scan of the original. The maps are clear and readable and it prints out very nicely for addition into your DM binder. They did a great job of digitizing an old classic!
The monster stat blocks are what you should expect, and used to with early D&D adventures. Short, conscise and easy to read. It makes converting to other editions very simple. Well worth the money for any grognards looking to preserve great memories, or for anyone else interested in some great D&D nostalgia.
