Description:

BOOKLET STAMPS: 1931 apparently commercial cover to London with extraordinary and rare franking of 3d green x7 (three with the Long Wing to Plane!! BW #B136d) & KGV 2d red tied by 'CREMORNE/22AP31/NSW' cds, superb 'SPECIAL/22AP31/=SYDNEY=' b/s, First Official Air Mail Flight cachet in violet, minor peripheral tears & part of the flap missing. The rate was Empire letter rate 2d per oz + domestic airmail 3d per ½oz x2 + Karachi-London airmail 6d per ½oz x2 = 20d (1/8d) so the postage was overpaid 3d, suggesting it was supposed to have been registered.



The variety units are the first (the Long Wing is obvious but the stamp is damaged at upper-left), fourth (the variety largely obscured by the cds & perf damage at top) and the seventh (the variety fully obscured, very fine).
