Jamaica. (British West Indies). 1900. Stamp-less Official mail envelope printed 'On Her Majesty's Service' with 'Dead Letter Office/ Jamaica' and 'returned Letter/Paid' addressed to Kingstown with framed 'Returned / Letter Branch/ Mr 9 00/ Jamaica' and Kingston/ Jamaica date stamp 'Mr 9 00' on reverse.
The printed envelope was used for mail that was not delivered and thus returned to the writer. An elusive Official printed envelope.
