The Salvation Army Antigua & Barbuda stamps 1988 were issued two weeks later with the Barbuda mail overprint. The FDC with all stamps on it has been know for a long time (SA 27.1a). The minisheet of General Eva Burrows overprinted Barbuda mail has not been seen before, but turned up recently on Ebay. The suggested number in the SA catalogue is SA 27.1b. Certainly a rare cachet!!
