I’m a fan of the vaguely-retro street signs the Downtown Alliance installed several years ago all over Downtown as part of a plan to improve wayfinding. The white type on black is classy and clean, the photos provide a visual link to familiar landmarks, and the address numbers are a big help. It’d be nice to see these signs in other parts of the city.
I found this collection of signs at a garage on Washington St that the Alliance uses for their shuttle buses.
