Hundreds of feet above the streets of Paris workmen make adjustments to the scaffolding surrounding huge new exhibition buildings - accompanied by a brave cameraman working for the Topical Film Company who obtained some scarily vertiginous images of construction at a time long before modern health and safety regulations. The film was originally released on 16 March 1931.
