Lineposters: Minimalist Subway Prints

I’d love a subway print like that in my town. Thanks for sharing!

Without
the station tags or some street labels on it, I think these are just
decoration pieces. They can only work for person who is well aware of the
cities and can read its map without the signs. But why would a person who is
well aware of the city need a map? Maps are usually for the visitors and
tourists. How a tourist can read this without any labels or indicators?
Secondly, nowadays we have free maps with better features on almost every
mobile phone, so again they are only decoration peices
