Quickie question... I was going through my French stamps last night (down to 9 major country collections to sort through/store now that France is nearly out of the way)... and I hit a couple of stamps that have the same overprint "F.M." (nothing else on the overprint).
Anyone know if that's specifically supposed to be "French Morocco"?
Or is there another possible meaning for it that I'm not aware of? (no scans at the moment, as I was running late last night at the house)
