Auction 321 - 332 Europe & Overseas Great Britain & British Commonwealth - Day 3

1919: Pioneering Aviation, French Morocco to France, cover from Casablanca to St Brieuc, Cote du Nord, dated 10th September 1918, with Casablanca datestamp and "AVIATION MILITAIRE / SERVICE POSTAL / du PARC / MAROC" boxed cachet in black alongside; no charge has been made so the cover was probably sent on military business; to reverse an arrival dated 15th September 1918, some tears and opening faults around edges, otherwise fine, a scarce early military air mail cover.
