I'd like to direct your attention to an absolutely splendid organisation. The History of Advertising Trust. A group of wonderfully eccentric archivists and librarians busily preserving the detritus of one of the most ephemeral and disposable industries there is. Most of their archive is stored in old Nissin huts in Norfolk, but they're rapidly getting stuff online, and it's stuff you can't find anywhere else. I especially love the Wilfred M Freyer archive. Be fantastic to see illustrations like this being done today.
The Star Cafe on Great Chapel Street has some examples of this style of work on its walls. Worth a visit for the food too.

for an American analog(ue), I'd suggest the "John W. Hartman Center for Sales, Advertising, and Marketing History" at Duke University:
