The book is open to a page with a detailed sketch of the mountains, with the peaks and valleys of the landscape clearly visible. The colors used in the drawing are mostly shades of blue and green, with some hints of yellow and brown. The mountains are depicted in a realistic style, with a few trees and shrubs scattered throughout the landscape. The sky is a deep blue, and the sun is setting in the distance, casting a warm orange glow over the scene.
