here is a photograph of the theater in the center, with a portrait of "proprietor and manager" John McCollough above it, surrounded by 19 portraits of actors. They are all identified in pencil on the verso. The verso contains extensive advertising, including 19 testimonials by subjects of their portraits. Here is an example: "The Canadians all swear by 'Notman,' the celebrated artist in Montreal, but they all acknowledge your photographs far superior to any he has taken."
