Note that the flag, originally, ran right up to the edge of the frame's lip, with some pull away on the right side.
You can see the wooden strainer attached to the aluminum extender frame. Also, you can see the "Z" bar cleat attached to the top member of the wooden strainer. It is from this that the flag frame is hung. Also visible is the white Coroplast platform hot glued to the front of the wooden strainer.
