Hand-drawn side view of an old stone well with a simple wooden windlass on top: two wooden posts hold one thin horizontal wooden axle across the top of the well. On the right end of the axle is one large wooden wheel with spokes, and one small crank handle on the rim of that wheel. A rope is wound around the thin axle and hangs straight down into the well opening, holding one wooden bucket of water just above the well rim. One child's hand turns the handle. Only these things: the stone well, the two posts, the axle, the big wheel, the rope and the bucket. Nothing else in the picture, plenty of empty space around it. Coloured pencil and watercolour marker, clean black ink outlines, warm off-white paper, no text.
