I found this on the Bonhams website which doesn't have a very good facility for saving pictures or pinning but if you click this link you will be able to zoom in and have a better look.
It was sold last year for £936 and it's obvious that they didn't know much about it as it is just described as -
A very large early 19th century cotton chintz patchwork quilt featuring a Mariner's Compass and star centre surrounded by a deep border of hexagons, smaller Mariner's Compasses and diamonds, of cream cotton and printed cotton chintzes of many colours and designs, backed with bue cotton, 285 x 328cm.
It doesn't appear to be quilted and doesn't look in particularly good condition but what a tour de force? I am always delighted to find one of these early patchworks and am facinated by the intricacy and marvel at how long it must have taken to make one.
