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.
