Travelling back from our holiday a few days ago, I amused myself by looking out of the window of the plane and watching Spain glide by below me. We all now take for granted the ability to look down on the earth from above, but imagine what a novelty it must have been 100 years ago. Whilst a still photograph mimicked little more than a blink of an eye and a moving picture was what we were used to seeing, before flight nobody had seen the world from above.
This is an early aerial photograph of Trafalgar Square in London. It has always inhabited the fringes of my collection : it is not a particularly rare photograph and there are no fascinating messages on the reverse. But imagine the thrill of those who received such a photograph just 100 years ago and knew, at last, what was meant by a birds' eye view.
