Sheet marked AT in red cross stitch

Country sheet of the 19th century canvas, in perfect condition, 1m90 by 2m75, marked at cross-stitch. The sewing in the middle testifies to the width of the looms of the time. A bit heavy and thick as a sheet for current tastes. But perfect for a sun visor curtain or for a large country tablecloth that will not fly away at the slightest gust of wind and will not fear washing at high temperature. A trace - see photo with a piece - which will leave over the washes. An old dry cleaner brand in a corner.
