Special Stamps

Denmark was neutral during the first world war (1914-1918), and to defend the Danish neutrality a large numbers of soldiers were drafted. Once a week every soldier got a free post card and from 1917 on a stamp for a post card or a post letter.

The cards were overprinted with "SB", which stands for "SoldaterBrev" - "SoldierLetter".

The stamps are overprinted with "SF" which stands for "SoldaterFrimaerke" - "SoldierStamp".
