The cover of the book 'Mapping the World: Maps and Their History' by Nathaniel Harris. The cover features a collage of three maps: a topographical map on the left, a world map in the center, and a geological map on the right. The maps are arranged in a vertical orientation, and the background is a gradient from light blue at the top to dark blue at the bottom. The title of the book is prominently displayed at the top in bold, white font, and the author's name is written in smaller text at the bottom.
