London Underground tube map, c1911 (by Mikey Ashworth, via diamond geezer).
One of the most interesting things, to me, is how much of the central network was in place by this point. The only tube lines built inside the Circle are the Victoria and Jubilee lines.
It’s definitely worth clicking through for the uploader’s notes on the style and the inclusion of the Brighton Railway’s Elevated Electric services, and for his set of Underground maps, including MacDonald’s Gills minimal/calligraphic sketch map.
Paul Mison's random stuff that doesn't go elsewhere. Is it microblogging, or microactivity?
(Previously known as 'tumblr is my sock drawer', for reasons that are somewhat unclear.)
