The postcards of W.G. MacFarlane are extensively catalogued in the second edition of “The W.G. MacFarlane Picture Postcard Handbook, 1902-1910” by Michael J. Smith, a book that is essential for the collector of this prolific Canadian postcard publisher. The series numbers shown relate to Mike Smith’s book.
The series of view cards that are of greatest interest to me bear the “Private Mailing Card" back.
Cards from this series sometimes come with a W.G. MacFarlane publisher’s attribution that states "Canadian Souvenir Cards, W.G. MacFarlane, Toronto".
The earliest card identified by Mike Smith in the view card series is dated July 16, 1902. A patriotic postcard dated 10 days earlier, July 6, 1902, is illustrated below.
