long mural on a wall next to an earthen embankment

long mural on a wall next to an earthen embankment. The area in front of the wall is overgrown with brown, dead-looking grass. The mural features two grayscale portraits. On the right side is a man wearing a green cap and a white shirt. He has a slight smile. To the left of him is a shirtless man with something wrapped around his neck and chest. He's holding a long object to his mouth, possibly a pipe or a musical instrument. The background of the mural is filled with green, black, and yellow abstract shapes. The sky is visible above the wall, and the sun is shining brightly.
