This is an original NaviStich unframed piece. This sailing boat Margate and Broadstairs in Kent.
Taken from Admiralty chart No.L(D5) 1183 - Thames Estuary, dated 1988. Hand-stitched onto an original used Navigation Chart. Any pencil marks, creases or stains are part of the natural patina of a used chart, although this is a very clean example.
The external mount measurement is 10x8 inches to fit a standard frame size. Please note the oak frame in the image is for demonstration purposes only, this will be sent to you unframed for you to frame yourself.
