Note that there are two items under this catalog number. The twined textile (or "blanket") that is described on the catalog card, and a small lot of charred textile fragments. The larger textile does not appear to be burned or missing any pieces, so it may be that the charred lot is misnumbered. Or perhaps it was previously wrapped in the blanket? Unclear.
