This drawing is a blueprint produced using a photographic process. A blueprint is a negative print showing white lines on a blue background. It was used by architectural practices from the 1870's onwards as an easy and convenient way to reproduce technical drawings of buildings for design and construction purposes. Use of the process declined after World War Two as other processes, which could reproduce drawings without distortion, became popular.
