Double-decker buses were popularized in Great Britain at the start of the 20th century and today the best-known example is the red London bus, namely the AEC Routemaster. By the mid-1920s there were about 20 different companies with buses driving all over the city. The largest of these businesses, The London General Omnibus Company (LGOC), sought to differentiate from their competition and painted their buses bright red.

While the building in this photo has a traditional design, the red bus strikingly adds color to the image.
