Biafra 1969: Air letter form franked with 1968 1st Independence
Anniversary 2 s. 6 d. postage, used from Owerri to Illinois, USA,
dated 5 December 1969, cancelled by "OWERRI" datestamp in black.
Some wrinkles as is expected and a vertical fold well clear of
adhesive. A rare commercial use. Note: The sale and use of the
unstamped aerogrammes apparently caused confusion, so later the
aerogrammes were sold pre-stamped with a 2 s. 6 d. postage stamp.
