Now made public, the Air Pictures 'Portleven Collection' is a unique collection of interwar aerial photos taken by little known aerial photographer, Arthur William Hobart, and newly digitised by the Historic England Archive. The collection takes its name from a misspelling of Porthleven in Cornwall where Hobart lived. It features 242 black and white aerial images showing the national landmarks, towns, industrial sites, construction projects and seaside resorts of 1930s interwar England.

There are also sports grounds, new housing estates and major national infrastructure such as Twickenham Bridge.
