A rare photo of a Dorand AR.1 observation aircraft, serving on the Macedonian Front of WWI. The original comment speaks of aircraft in 'Greek colours', but actually, French insignia were worn here and units, including Escadrille 532 which was based at Gorgopi (or Gorgop) in 1918, were Franco-Greek, with mostly French pilots and personnel.
