When commemorating the Salvation Army Centenary in Guyana, four orchid stamps were overprinted with “Salvation Army 1895 – 1995”. The official FDC has the usual coat of arms print. The shown FDC has an extra Red Shield sticker, not seen elsewhere. In addition to the official PO cover, the Salvation Army Philatelic circle issued a specially designed cachet for the anniversary. Both covers are rarely seen on auctions. Estimated value with the sticker is £50 +
