These images shot in 1929 were probably included in the long documentary Angola, released in 1931, which no longer survives. The film illustrates the benefits of scientific colonisation and shared development stressed in these discussions by showing the health and sanitary conditions available to both the Portuguese settlers and the indigenous population. Under the benevolent Portuguese flag the native chief expresses his thanks for the benefits colonisation has brought while the children in the schoolyard learn Portuguese folkdances.
