[Healeys] Interstate Highway Map for LBCs

[Atkinson, Robert]

Planning a long distance trip in your Healey or other LBC next year and
familiar with the London Underground and it's iconic map?  Then consider this
rendition of the US interstate highway system in the form of an Underground
map (There is also a US numbered Highways map in the same style.)  No
financial interest...just stumbled across this looking for examples of great
graphic design for a class.
