Signage references

I recently found Corporate ID manuals for the London Underground. They're very detailed, with extensive information about signage (and how they organized them) - I found them inspiring, and I think they might help answer some of the questions posed in Monday's class. Here are the links to the PDFs:

And, something fun (and unrelated to the Corp ID project):
