Mission (Warnock?): Landscape with Mountains and Foreground Trees (from Sketchbook)

Pencil sketch on paper of trees, some very tall and thin. The sketch is in a sketchbook with some handwriting in the top-left corner. The trees are drawn in the foreground. In the background, there are some indications of mountains. The sketchbook page is off-white and the sketching is done in light gray pencil. The sketchbook has a black cover and is open to a page with a rough sketch. The background behind the sketchbook page is white.
