March 20, 1939 Air Mail Registered Special Delivery cover from Clinton, Ontario to Vancouver B.C. 3 different RPO back stamps to get the cover to Toronto & then it was flown to Vancouver. Addressee was not found, so the cover was returned to sender. Cover was 3 cents over paid, but is collectible as the Special Delivery fee was paid by E9 during it's correct one moth window period.
