I saw these two "Take Notice" installations on street poles around Elgin and MacLaren yesterday:
Looks like Coyote has seen them, too. One is his picture of the day today.
Looks like Ottawa has a new street artist in the neighbourhood (or at least a new campaign by an old hand). I'm not sure if the images have a specific message, or if "take notice" is simply an instruction to the people who are so tuned out that they don't see these creative invaders as they walk or drive down the street.
Either way, I think it's a good message.
