The menace of colour; a study of the difficulties due to the association of white & coloured races, with an account of measures proposed for their solution, & special reference to white colonization in the tropics,
A 1925 study by geologist J. W. Gregory, published in England, on the difficulties arising where white and coloured races live together and on proposed remedies, including white colonization in the tropics. The pictures are plain black-and-white halftone photographs of a university hall and dot-shaded world maps of racial distribution and population density, with explanatory keys and captions, which a designer might use as examples of dense, dotted tonal mapping and of sober early-twentieth-century institutional photography.
