27 RFC and RNAS aerial shots from WW1, each measuring 20 x 15.5cm or bigger. Some stunning battlefield shots, destroyed towns, trench systems, fortifications etc. A couple stamped 5 Wing RNAS others appear to be 49 Squadron R.F.C./R.A.F.
Note, images in were taken with a digital camera, not scanned so actual photos are a bit sharper; as you’d expect with aerial photos. However these should give you an idea of content of the lot.
