This sounds like something for you Macinnis!
UK based street artist My Dog Sighs paints portraits on crushed cans found on the street. He paints a unique face on the can’s bent-over round part – giving each one its own personality and then leaves the artworks on the street for people to find. My Dog Sigh’s project, called FreeArtFriday, has spread throughout the world, with thousands of members now participating and turning the streets of their towns into a fun, free art show.
Check out more of his art cans at his Facebook photo gallery.
