STREET SCULPTURE-IS IT ART OR JUST A PILE OF METAL?

Wherever I go, I look for images and well- art. During a recent trip to Toronto, I photographed this street sculpture.

Was it pieces of metal left over from a construction job and cheaper than going to the dump for the contractor? Does it conjure up any thoughts or ideas about life, relationships or the environment?
How does it compare to other street sculpture you have seen?

Like the big spider in front of the National Gallery in Ottawa Ontario- our captial! I love the size. In other countries there are huge pieces of art displayed in public places. Sometimes a major theme like a statue of a famous person is the centre of an area!

Here's Sir John Alexander Macdonald- the first Prime Minister of Canada,1867- in a park in Kingston Ontario! He actually had a huge long cobweb hanging from his nose to his hand. Does it tell us something about how people are old history? Can not say ancient about Sir John! Or are there just a lot of spiders making webs? What art and images do you see and like in your community?
