Old printed cotton feed sack from Wasseo, chicken mash concentrate with somewhat faded red and blue graphics.
This has been opened flat, original chain stitching removed. The fabric has soil and spots - it's right out of a Wisconsin barn hayloft where it's been for about 60 or 70 years!
Sack size is marked 100 lbs.. This measures 21" across the width as a sack (42" wide fabric) x 40" long.
