vintage cotton chicken feed bags, feedsacks w/ red & blue printed advertising graphics

Lot of two (slightly different) CO-OP chicken mash bags, 1950s vintage. These are feed sack fabric, unbleached natural color cotton with graphics in red and blue, somewhat faded.

One bag has been opened flat, one is still sewn up as a sack. Sack size is about 19" wide x 38" long. Both have a few spots and small holes, but are nice and clean.
