Good lot of 20 pieces related to the British R.F.C. during World War I. Included is: period signature cut from a report of Major GEOFFREY H. BOWMAN (1891-1970), a British ace credited with 32 victories; five typed 'Combats in the Air' reports, all bearing the narrative but lacking the signatures and bottoms of pages; six modern prints of wartime photos of noted British pilots; the balance being modern postcards and commemorative covers. Very good.
