Found these two groups of labels in an old album purchased at an estate auction yesterday. Not much else really interesting in the book, but these were a pleasant surprise.
Collection of 14 Prime Ministers of Canada up until Lester Pearson. That would date these pre-1968. Possibly produced for Canada's Centennial, although they do not sport the centennial logo.

Also a complete collection picturing the official flowers of the 10 provinces and (then) 2 territories.

Not beautifully designed, by any means, but at least both collections are complete.
