Now go outside and look at the sky.
During my travels in China I was always fascinated by Shanghai's history and by how close to the surface of modern Shanghai much of its past still is.
It's still possible to find pre-revolutionary signage on some store fronts in the more quiet side streets and a lot of the building substance of the 1940s has survived - even with a war, a communist revolution and the storm of modernization that has been unleashed in the 1990s.
Shanghai in Images is a collection of historical photographs mostly from the 1920-1940s with many bustling street scenes and interesting views of old Shanghai.
And Shanghai's Historical Western Architecture is a project to document many of the major historical buildings. The pictures were taken in 1994 and many are high-contrast black and white pictures that have the same quality of light as most historical photos.
