12pp (on heavy stock) of route maps with advertisements verso, ring bound board covers. In very good condition. This flip map is very rare and would have been used by passengers to follow the route whilst flying from London to Paris. As well as the maps there is information for passengers about flying in general, such as why sometimes flights are bumpy, how to clear one's ears as the pressure rises and falls and so on. The advertisements include ones for spark plugs, whisky and even your own private aeroplane!
Imperial Airways ran from 1924 to 1939, it became BOAC and eventually British Airways
