npub1dm5seg0ukscz6zvhrfe6497ka2xdsqwt57nfnvuxu9pxkv25sngsdw5sqe (npub1dm5…5sqe) I'm not really on Instagram anymore, but there was an account that was all about photographing sewer covers (I believe in Europe). I realized that there is quite a bit of design and artwork that goes in to the big, round, iron covers; usually depicting the city or local landmark.
This is a photo I took of one from Ann Arbor, MI (Tree City).
