(Temporarily) Listing of cancellations and postmarks concerning Clément ADER - considered by the French as having built the first powered airplane. This will not be discussed over here, nor the stamps depicting Clément Ader, but just cancellations. His plane was based on a bat-wing. Most of these cancellations have been depicted in this publication before, but it was good to put them together, check dates of the items in my collection, and now wait for corrections and additions!
