Long before John Lewis and Debenhams came to Oxford Street, there was Marshall & Snellgrove. This luxurious store was founded in the 1800s, with many other branches later opened around Britain. After struggling throughout the war years, it merged with Debenhams in 1919.
I really like how architects Grimshaw have utilised the card tubes, commonly used to hold fabric, in their design for John Lewis. Google Image Result for http://static.dezeen.com/uploads/2011/09/dezeen_John-Lewis-Fashion-Pavilion-by-Grimshaw_01.jpg
