Hand Painted flour sack primitive prairie sleeveless dress school room Greta

Very unique and beautiful sleeveless longer length dress made from what looks like flour sack material with hand, painted design of an old-fashioned school house on the bottom side and a teacher across the chest The ties on each side of the waist make this dress somewhat adjustable. I am a size large and it fits fine but if tied tighter, it could fit a smaller size. Some minor spots/stains but otherwise in good condition. need to be ironed! There seems to be one of a kind or rare signed by Greta
