1903-04 Imperforate Plate Proofs of Local Design
For the first time during the history of the Straits Settlements, local designs were introduced. These designs were prepared by Mr Noel Trotter (Postmaster General of Straits Settlements) and Mr W Egerton (later Sir Walter Egerton, Governor of British Guiana).
Proofs are produced to enable the engraver to see that his work are reproduced as he intended, for submission to the printers for technical approval, to the issuing authorities for approval of the design as engraved on the die, and also for record purposes. These documents are of great philatelic interest, as they are rarely available.
