Watch your step – you might be surprised 21 April, 2009 by sky Leave a Comment Walking down the street a couple of months ago, I was amused to notice this manhole cover in front of the Museum of Modern Art. Brightly colored at some previous time. Art is everywhere. How many people think about manhole covers? Not many, I guess, but there are a few… Illuminated manhole cover so you don’t fall in at night, especially if you’re old. Manhole covers as art.
