Photo is of the Shanghai Jardine Silk Factory between 1910-1912, where the manager and his wife pose for a photograph among the rows of silk reeling machines. This silk factory and the later cotton yarn factory were important parts of Shanghai’s early industrial output, and one of Jardine Matheson‘s earliest industries, exporting silk to various parts of the world.
