Manhole Cover Designs

As described in my Signs Afoot 7 April 2009 blog post, I am interested in the design and age of signs and marks under foot in a city.  I have recently collected images of manhole covers from Marrakech, Morocco to Portland, Oregon.  I am delighted by the variety and personality expressed in this most-humble of civic street elements.  Here are some of my favorites:

Portland, Oregon

San Francisco, California

Palo Alto, California

Salinas, California

Marrakech, Morocco
