Another famous early slide maker was J. T. (John Thomas) Norman, in business professionally by 1846, and working continuously until his death in the early 1890s. His successful commercial business was then carried on primarily by his son Alfred until the 1930s.  He used a variety of beautifully patterned and coloured cover papers, especially in the early days of his mounting career, as illustrated below. It is known from business records, that he was also the actual maker of many slides which were sold by other professional mounters under their own labels. Many of Norman's slides were also factored through various retail optical shops, and often carry their secondary labels.
