This fonds consists primarily of historic postcards depicting landscapes, buildings, attractions, infrastructure, and vehicles in the region of Southwestern Ontario, with a particular focus on Windsor and Essex County. Many of the postcards are undated, but formats include hand-tinted Early Twentieth Century (ca. 1900-1914) and White Border (ca.1914-1932) styles, as well as Linen (ca.1933-early 1950s), Standard/Chrome (ca. mid-1950s-1970s), and Continental/Modern (ca. 1970s - present) styles. Also included are a small number of photographs and ephemera items including arrest warrants, tokens, medallions, patches, maps, brochures, tickets, and advertisements, all relating to local people, businesses, events, or locations.

The years 1900 to 1914 were a so-called Golden Age for postcards in North America, thanks to the popularity of photography and mass production techniques that made them an affordable collectible item. Views of all kinds were produced, including residential neighbourhoods, churches and civic buildings, commercial districts, industrial plants, bridges, and landscapes. From 1900 into the 1930s, many postcards were black-and-white photographs with colour added. In subsequent decades glossy colour photographs became the norm, and a narrower range of views were produced (often depicting popular tourist sites, where they were sold as souvenirs). By the 1970s most North American postcards shifted from the traditional small size (8.5 x 14cm) to the larger European (“Continental”) size (10 x 15.5cm) and continued to feature a small range of local tourist attractions. All of these trends are reflected in the postcards contained in this fonds.

This fonds principally contains records connected with the Congregation of St. Basil (Basilian Fathers) whose members administered Assumption College and Assumption University from 1870 onward. Secondarily, it contains varied records that document the history of Assumption and its evolution over time. Included are legal documents, memos, correspondence, ephemera, constitutions and rules, historical narratives and memoirs, reports, and a variety of Basilian publications and formal histories of Assumption. Some items pertain to Catholic education broadly, or to the history of the Catholic Church in Southwestern Ontario. Of special note are Assumption fight songs and a victory song, and the Second World War war diary of Rev. Mike Dalton, a military chaplain.
