Hi Hereward
I am not sure about the reason why. The various French postcards I have photos of, if used, are invariably stamped on the picture side rather than the side we are used to. I have looked at quite a few different postcard selling sites in doing my research and this seems to be standard practice.
Best wishes
Roger
