caption: The image shows an open book with a drawing of a tree in the middle of it, set against a black background. The book is likely a sketchbook, as it is open to a page with a detailed drawing of the tree, likely created by Joseph Mallord William Turner. The tree is depicted in great detail, with its branches and leaves clearly visible, and its trunk and branches reaching out in all directions. The black background provides a stark contrast to the white of the drawing, making it stand out even more.
