1928 #CL30f “RED LAKE” on Patricia Airways Exploration tied by Rolling Portage, Ont (MY 2 28) with 2c Confederation to Red Lake with red backstamp. Address is written in pencil and lightly erased. Overall toning. Note in Unitrade below listing states “CL30 inverted overprints $200, $300 for NH” which is 2.5 to 3 times regular stamp price for this variety. Presuming the same would apply to covers, this would be CV $ $750 to $900. A rarity, especially on cover.
