UK Aerogramme with Enclosure

This aerogramme (Greiner UK #17) was sent from LONDON W.C. (machine cancel 18 NOV 195?) to Sidney, Ohio/U.S.

The aerogramme contains an enclosure, a newspaper clipping, which was against the rules for aerogrammes. The aerogramme was handstamped “Contains Enclosure / Forwarded by / Ordinary Mail” in red and the “by Air Mail” routing instruction was crossed out with a red six bar handstamp. Aerogrammes containing enclosures were diverted to surface mail.
