Two Sketches: One of a Turtle, the Other of Two Unidentified Objects

The image shows a piece of paper with three drawings on it. The largest drawing is on the right side. It depicts a turtle viewed from above, facing left. The turtle's shell is mostly brown with pink and green patches. The turtle's head and legs are visible, and its tail extends to the top right corner of the image. On the left side, there are two smaller drawings stacked vertically. The top drawing shows a detailed sketch of an unidentified object. The object appears to be a mechanical component with a rounded rectangular shape and three circular indentations on its surface. The bottom drawing shows a similar object but viewed from the front. The background of the paper is yellowed and has darker spots.
