Thematics, Air mail., Covers. A magnificent collection of air mail postal history exploring the 1934 APEX with several dozen items well researched and written up, as well as a wealth of scarce collateral material, all displayed on a large stack of exhibition pages. Highlights include an interesting rocket post section, an important study of the early London autogiro flights, including destinations to Cape Town, Iraq, Egypt, etc. Also a rare 'first philatelic autogiro flight' cover signed by pilot from Hanworth aerodrome, as well as original flight labels in tête-bêche blocks, etc. 25 years in the making, there are a good number here that have cost the vendor in excess of 100 € each. A highly recommended viewing. (Image1)
