The Orta Saint-Hubert G.1 was a Belgian light aircraft designed by Jef Guldentops and produced by José Orta's company at Saint-Hubert airfield in the Ardennes. At least 15 examples were built. This machine of the Antwerp Aviation Club carries advertising on the fin for ARPIC, a member's automobile parts company. The photo source claims the photo was taken in Antwerp, but this is a Schiphol hangar. Photo from: Nederlands Instituut voor Militaire Historie
