The Southport Citadel Corps celebrated its centenary in November 1993. To commemorate this milestone, a special centenary logo was created, along with a unique cachet designed by “Salvation Army Covers.” This celebration coincided with the release of the 1993 Christmas stamp set, which was issued as a FDC. Here is the original cachet (catalog value £15), along with two others featuring the special postmark used on different cachets (cat. value £10 each).
