This is a very rare original antique Wm Low & Co The National Grocers pot jar from the late 1800's. William Low was the grocery store before Tesco took it over. The front is signed Wm Low & Co. The National Grocers. The back is stamped 2 LB GRAY A PORTOBELLO NB. It is stoneware pottery and measures 5 1/2 inches or 14 cm in height and 6 1/4 inches or 16 cm in diameter. It is in great condition considering it is over 150 years old. It would be a wonderful addition to a collection. It is a very rare piece and is a superb example of it's kind.
