gravel pits and cloud formations

Photos of clouds from the Allen Aerial Photograph Collection at the Ashmolean Museum:
Major George Allen (1891-1940) was one of the first people in Oxfordshire to own an aeroplane - a De Haviland Puss Moth, named 'Maid of the Mist'. He flew extensively across Southen Engand ... taking aerial photographs from 1933 until 1939.
Many of these photographs are of archaeological sites but he also took photographs of towns and cities, racing circuits, gravel pits and cloud formations.
There are more than 2000 images you can browse online.
