    Good content, very small print and photos
    Format: Paperback
    Get a magnifying glass… the print is tiny. They must have made this book to be a large hard cover because both the print and the photos are so small in paperback. Content looks decent. It’s a gift for my grandson who will probably spend more time with the photos than the reading anyway and his eyesight is better than mine. :D
