2010: I wish the photo was better. Sometimes a bulletin board can be simple. White background and red strips. I did use an overhead projector to mark the center points for the stars on the blue flag. I saved the strips and the blue and re-used it.
2012: A take off from on of my political cartoonists, Robert Matson. You can see the original here.
2013: Simple and understated, no text or images.
