Collection contains over 55,000 glass plate negatives, film negatives, and prints from the Waldren Studios of New Glasgow and Antigonish, Nova Scotia. The majority of these negatives are portraits, nearly all of which are identified and dated. A number of the portraits represent some of the earliest photos of Black Nova Scotians from Pictou, Antigonish and Guysborough counties. Many of the remaining photos are local scenes, a few of which were taken in New Glasgow before the fire in 1874 which devastated the town. The collection contains photographs that depict show coal mining, shipbuilding and other local industries in action. Portraits of family groups, sports teams, social clubs and school groups are also well represented.
