Here's an interesting pocket Bible. It was given away to soldiers across the British Empire during World War Two by the British and Foreign Bible Society. This one to a soldier in the Australian Army.
It cannot be rare, however I am unable to find any identical in the online catalogues of the usual Australian cultural institutions. If you know of any similar examples - please let me know.
This one bears the symbol of His Majesty King George VI. It is 120mm high and 76mm wide.
Inside the front cover is a tipped in presentation page plus a stapled Bible Reading hints insert. The slightly corroded staples have created a slight brown stain. Otherwise the bible is almost unmarked after 70 years:
His Majesty's message to his loyal troops is also included. The message is dated just 2 weeks after the start of World War Two:
Interestingly it was printed at the University Press, Oxford:ntegrated Catalogue of the British Library and cannot find it there either.
