Morning all. I need a little help in identifying an interesting 'Aerienne' slogan postmark on the 75c 1925 Decorative Arts stamp from France (SG410). See photo below.
The postmark appears to be in three lines, reading down from the top there is AERIENNE, RENSEIGNER DANS -, ?S BUREAUX DE POSTE.
From Google translate I think it is an advert for airmail services, for the public to ask at the post office?
Any info regarding the full postmark and it's dates of use would be most appreciated.
