The street art in Toronto – murals, graffiti – is worth a book on its own (I should check – it’s probably been done already).
Here is one solitary but quite lovely example – appropriately enough, high on a wall in a quiet downtown side-street.
Street Art, Toronto
If there is still a book to be written, you are certainly qualified to do it proud. BTW, I have several shots of decent quality from our last trip to the open market.
Perhaps it will be a future project…. You should post some of your images, too.
