Beck's Paris Metro map

I'm sure I've seen the map in print well before the 2008 date quoted in the article (tho' I can't remember where at the moment). Two immediate points of interest: one, given the discussion elsewhere about the range of available colours, is the number of separate colours used for the 13 1/2 lines that the Metro then had; two, compared with London, the individual lines in Paris often follow quite tortuous routes (eg the 4 and the 8 for example), but Beck quite brilliantly brings some order to the whole thing.

There is a similar map published in the appendix of Mr Beck's underground map, however this doesn't show the Seine in it. Seemingly he worked on Paris from the late 1930s to early 1950s without convincing the authorities.
