Australian Aerogramme Used in the UK
"Form not approved ..." - Diverted to Surface Mail

Australian 9c aerogramme (Roggenkämper no. 26) issued on Nov 23, 1966. Used from CATFORD SE6 (cds 17 AUG 1967) in the UK to Elizabeth West, South Australia.

Royal Mail detected that an Australian aerogramme was used, h/s “Pattern of form / not approved by P.M.G.” and cancelled the “Aerogramme / By Air Mail ...” legend with six parallel bars to indicate the diversion to surface mail.

Neither British nor Australian taxation marks.
