France WWI: Early Monoplane Pur de Dome Volcano - Prix Michelin? (Unique Vintage Glass Plate Negative 1910s)

spectacular and ultra rare original historical glass plate negative measuring approximately 12 x 9 cm. this unique photographic masterpiece from the early aviation era captures an early monoplane aircraft flying at low altitude over a rural field.
the background features the iconic silhouette of the puy de dome volcano in auvergne, france, with buildings visible near the summit. the image likely documents the historic michelin aviation prize flights circa 1911 or early reconnaissance military training in the region.
the glass plate is in good vintage condition with sharp details of the aircraft and landscape. it features a minor emulsion scratch in the sky area and typical vintage edge handling marks consistent with its age. a premier museum-grade piece for collectors of early aviation history, experimental flight, and pioneering monoplanes.
