Vintage original photo, 9x7", b&w. Aerial photo with what may be a British biplane below which itself is above trenches. In the negative is "Reproduced by Photo Sec. 11". On reverse in ink:"R.E. 9 (?) hedge hopping on the way home after artillery reglage". (The identification of the specific model is unclear because of handwriting). Most unusual to see an aircraft in an aerial photo since most are of ground subjects. Very good.
