With at least some hint of reference to McIsaac's post from a few months back—and our work for our regional government of the same name, Metro—we simply thought this was interesting. That's all, nothing more. A collection of logos identifying metros (urban rail transportation systems) for cities worldwide, including Portland's own TriMet. Perhaps the assembly was compelling because it dredged memories of our epic study of another letter (that being the letter T) for Tidewater Barge Lines which was in full swing at about this time last summer. I forget, was it ninety eight variations on the letter T? Why, yes. Yes, I do believe it was at least ninety eight perfectly appropriate Ts. But that's another story altogether. One that will be told with some vigor, I can assure you. Image and metros story by way of Quipsologies.
