A Hut or Sheep Pen in the Woods, Adriaen van de Velde, 1646 - 1672
This looks like the same rickety structure seen in the painting The Hut, only from a different angle. Van de Velde probably made a number of sketches on the spot in the open air. One of them was used for the painting, while another served as an example for this meticulous and detailed drawing that was meant as an independent work of art.
