Marks in time: 125 Years of Marks & Spencer

A fascinating glimpse into the history, influence, activity and success of a national treasure. 50 short, heavily illustrated stories will cover such diverse topics as technical innovations, democratisation of fashion, the power of advertising (M&S can predict what a high percentage of the population will eat in any given week), the war years, the revolution of mass-produced food, ecommerce, customers, staff and social history (the M&S archive has a bigger collection of utility clothing, for example, than even the V&A).
