Alternatively, some factories found it profitable to sell 'blanks', unglazed/undecorated pieces which other companies bought and decorated in their own designs, which is why sometimes you get one companies' backstamp over anothers impressed marks. This is also why you see a lot of utilitarian wares, dinner services, tea sets and the like, which are impressed with 'Made in England' and then sometimes backstamped by the factory that decorated them. Johnson Brothers and Meakin did a lot of blank production, which is why their everyday wares are usually backstamped with the factory name and have the impressed Made in England mark.
