Proud Bailey

​​​​​​​Edward Proud founded the Proud Bailey Company Ltd in 1961 through which he published a number of handbooks covering the postal history of over eighty different British colonies and which illustrate over 50,000 postal markings. In publishing the series of books the major reference used for postmarks was the Springer collection which in itself attempts to show every postmark, early and late date, used by each post office in every British Colony or Protectorate up to independence.
