I keep an optimistic  eye out for stylish manhole covers, though well designed ones are rare finds outside of Japan.  But then I saw three of these wonderfully fishy-man ones on the corner of Jervis and  West  Georgia Street, Vancouver. Perhaps there are more, somewhere else. I hope so, I am in complete agreement with the evolutionary aptness of the fish-ancestor and the seethy sea and river feeling of abundance. Bravo.
