New favorite thing

I was recently waiting for a bus by one of the ordinary glassed-in bus shelters on Walnut, when I noticed that on the outside of the shelter (probably opposite the posted schedules) was a neat new feature that must have come from a collaboration with the city's historical archives: it showed the opposite corner photographed some time in the 1940s, along with a matching photo of the building currently on that corner, and offered some historical chat (who was President and other trivia from the earlier time point, what changes in the neighborhood led to the razing of the old building and the erection of the new stuff, etc.). Will try to get a photo at some point, and will be on the look-out for more of these. Great idea!!
