Antique Mohtasham Kashan Rug - Very Rare Design c.1890

Very scarce overall pattern mohtasham Kashan rug virtually devoid of any floral designs instead being virtually abstract in nature. I have never seen another pattern quite like it for a Kashan. surely one of a kind! Dark blue indigo ground colour. kurk velvety wool pile with abrashed band. has a stunning overall mesmerising look. All over low even pile throughout. both ends been blanket stitched. Plenty of images of rug. Transfers, discussions, viewings, etc all welcomed
