G. H. M. & Co
1/ 12 1901
Another image contributed by Frank Sente. This time a December 1901 Mumm printed cancel with a stark printing variety. Notice the "ghost" image of cancel at end of "FRANCE" and 1901. Frank believes this may have been caused by a foreign substance on the sheet which later came off, leaving nothing but a ghost image. This explanation would mean this variety is a "one-off" and not a repeated variety.
