Avebury restored showing three circles full of stones, one of the avenues and Windmill Hill Image credit: Alan Sorrell – Old postcard Chance Mar 8, 2011
Chance - this was actually by the late - and in my view, great - Alan Sorrell (1904 - 1974). Perhaps best known for his castle reconstructions, which is how I got to know of him as a kid in North Wales.
Copied from the Flickr Prehistoric Postcards collection where many more can be viewed.
