The centenary of the Salvation Army Movement in the Isle of Man was commemorated on four stamps in 1983. General William Booth is featured on the 12p stamp. The founder visited the island in May 1897. Four official postmarks were used, Douglas, St. Sanctain, Ramsey and Castletown. The shown FDCs here have gutter pairs and Ramsey PM on the official post office issue. FDCs with gutter pairs are quite rare.
A few countries have issued Salvation Army scout covers. I have now listed those I have collected here, see also the menu. It is mostly Norway and Sweden who have the tradition of making a special PM to the national scout camps. The catalogue numbers refers to ArGe Pfadfinder’s catalogue about European scout covers and postmarks. The below cover is the first registered Norwegian scout PM; issued at the “Concordia” international girls’ guide camp in 1954.
Faces of Australia official Post Office FDC issued 01.01.2000 with three pictorial postmarks: 2 x Sydney (Opera and Clock) and 1x Darwin. Extremely rare with PMs from different locations!!! How on earth did they do that?
