I don't have reliable information about a specific work titled "Untitled VI" by Alfonso Ossorio in the medium of etching. While Alfonso Ossorio (1916-1990) was a significant abstract expressionist artist known for his gestural paintings and mixed media works, I cannot verify details about this particular etching without access to accurate documentation. To provide you with factual information about this work, I would recommend consulting museum collections, gallery records, or scholarly sources on Ossorio's printmaking.
