Complete First Six Sets of Airmail Issues, all mint hinged except for the key set C54-60 which is never hinged. Includes both the white and grey papers of the first set (as described by owner). A very fresh collection, with bright colour, and the hinged stamps are very lightly hinged (a few hinges fell off by themselves and left barely a trace). (Image)
