Vintage PIGGY COUNTRY CURED HAM, Ham Cloth Bag Sack, 

NEW Old Stock, some occasional wrinkles from stacking after sewing--see images

Heavy weight muslin, 20 x 13 inches (largest dimensions).  The color is actually off white, there camera is making them look cream.

Apparently, these were manufactured for export hams as all of the information is both in English and French.
