Beautifully Written-Up Collection of Commercial Airways Stamps, with an introduction giving a history of this airline with maps, photographs, etc. See scans for the many nice stamps included, including proofs, blocks, complete panes (some seldom seen), with a mix of hinged and never hinged. A nice collection, and the catalogue value is conservative. (Image)
