If I lived on a street called Smiley I might have to do something this exuberant myself. Maybe not this exactly, but something certainly!
This a private home so I didn’t approach any closer to look for signatures. It’s relatively new, as it does not currently appear in Google street view (in a photo dated April 2014). The writing says “Thanks Happy Day.” Located on the east wall of 825 Smiley Street, at the corner of 9th Street N.
