The images here come from an 18-page, pocket-sized booklet aimed at visitors to Portsmouth called Harbour and ‘Victory’ Tour.
As you can see from its cover it cost 6d (2.5p) and it was printed by Clarks, of St James’s Road, Southsea. But nowhere does it give the date of publication.
It contains a lovely reference to Paulsgrove for visitors taking a harbour boat trip: ‘Beneath the white chalk cliffs in the hillside are a group of trees known as Paulsgrove, close to which is the spot where oil-boring was abandoned in February 1937, after a depth of 6,556 feet had been reached.’
There is also this picture of the fourth HMS Illustrious entering the harbour. She was commissioned in 1940 and served until 1954. This gives us a rough idea of the date of publication.
Thanks to Eileen Barnes, of Sheet, Petersfield, for passing on the booklet.
