This is a full newspaper sheet (from "The Mail" later known as "The Globe and Mail"), with P. T. Barnum’s ad of course being the largest on the page.  There are also some REALLY interesting reads of unrelated news stories of the day.  

This ad is promoting his “Great Roman Hippodrome” show, in the summer of 1875.  It is billed as the first tour in Canada, The Great West, and The New England States, to major centers that are only available by rail.  A fantastic display piece that will be shipped rolled in a mailing tube.  My picture is your indication of the pages condition.
