Talk about taken-for-granted details! The ubiquitous manhole cover is SOOOOO overlooked, no one has yet invented a politically correct (non-sexist) name for it.
It seems that most covers, these days, are made in India. How did China miss this market?
If you have a little time on your hands, go to Flickr and search for manhole covers – you’ll be amazed at the variety, artistry and imagination lavished on this lowly detail!
