Canadian Picture Postage stamps are valid for postage but are printed in much smaller quantities than general-issue stamps and sold by Canada Post at a premium above face value to the stamp's client. Picture Postage stamps have been used to commemorate family events, anniversaries, historical events, organizations, charities, causes, hobbies, wildlife and animals, and many different themes. For thematic or topical collectors, a Picture Postage stamp can fill that gap in your exhibit or collection.
