1939 inter- bank censored envelope to New Zealand with a 6c cancelled KUCHING 1 SEP 1939. The cover has been censored with a double ‘uncut’ censor tape. Cancelled 1 September, this was the day Germany invaded Poland. Great Britain and the Empire only declared war on Germany on September 3, but this cover was censored !! This must definitely be the earliest possible censor cover out of Sarawak. A wonderful piece of postal history.
