Portrait of a blonde, English, 1932.

Vivex colour print by the English portrait photographer Herbert Lambert (1881-1936), from negatives taken with the Vivex automatic repeating back, devised by C W Oliver in 1930. During the inter-war years, manufacturers produced a range of materials for taking photographs in colour. The Vivex colour print, devised by Dr Douglas A Spencer (later managing director of Kodak), was based on carbro printing (one of the first long- tone printing techniques) and represented a significant development.
