These aerial photographs were taken from an aeroplane. One shows a German hospital and the other the entrenched main square of a town. the hospital photograph is marked ''L.Flt. A548. 45 NW. G 26 central'.28.10.18. 12.20". The main square entrenchment photograph is marked ' L.Flt. A531. 44 SE. R19b. 28.10.18. 12.20". Presumably these are number of photograph and the position and time taken.
