Chinese carpet teal blue

Teal blue carpet 9' x 12' bought in Hong Kong in 1971. Pattern hand shaved into thick wool in the center and corners. Was professionally cleaned in 2019 but still has some staining due to age. Mesh backing was damaged by a cleaning firm in London in 1996 but we were advised in 2019 that it should not be removed or the pile could be damaged. It is an extremely heavy carpet and requires at least 3 people to lift it. Viewing welcome. If any interest it will be cleaned before collection.
