Happy Manhole Monday! Today’s post is an excellent example of extreme 3 dimensional letters found on manhole covers. I have taken details of each because I was so surprised by the depth of the letters. As seen in the cover from Boston, a couple of the counters are filled in. See any crazy 3D type on manhole covers in your city? Take a picture and tweet it to me @nikki_vz to be featured in an upcoming post!
