The McGill Poster Collection documents posters and ephemera announcing campus activities, primarily in the 1970s with some 1980s and 1990s material present.

The fonds consists of a Strathcona Prize Plaque from 1939 and a scrapbook compiled by Dorothy Graham McCaig during her time at McGill, 1936-1937. Notably the scrapbook includes news clippings and memorabilia of the Student Peace Protests.
