Panel Bracket Square Metal Sign

About the Bracket Square design

Two rings of white L shapes nest inside a thick steel border, and every L turns its corner outward. The outer four hug the corners of the panel with wide gaps between them, while the inner four crowd close around a solid steel square, parted by only thin strips at the middle of each side. The inner ring looks like the focus marks in a camera viewfinder, framed again by a larger set.
