Before the development of plastics, pottery was the ideal promotional material, being attractive, durable, cheap and hygienic. In the 1800s, brewers and distillers were major customers for Lambeth stoneware bottles and barrels featuring their brands. By the early 1900s, the Burslem factory had a huge business supplying Kingsware flasks for advertising purposes to leading whisky producers, such as Dewars and Greenlees. There are around 50 different promotional flasks to collect with subjects as diverse as Dickens characters and iconic Scottish themes. D & J McCallum whisky commissioned their Highlander trademark as a Kingsware jug around 1930 and this prompted Art Director Charles Noke to create his renowned collection of face jugs or character jugs.
