The postcards of P.D. Ayer are catalogued in Mike Smith’s The Canadian Patriotic & Heraldic Postcard Handbook 1897–1945 Volume 1, a book that is essential for the collector of this Canadian postcard publisher. The series numbers shown relate to Mike Smith’s book.
Series 7 shows a bulldog on a Union Jack on the mast of a ship at sea. The earliest recorded postmark in my collection is May 17, 1904. Mike Smith has recorded 6 cards in this series.
Cards from this series come with a variety of different publisher’s attributions on the reverse of the card.
Cards of Ontario scenes are less common than those from the Maritimes.
