We know about the "Secret 3" early 30s radio show sponsored by 3-Minute Oat Flakes, but we've no clue about this piece which in addition to the text features a numeral 6 at the center with an arrow through it. The six-pointed brass star badge is 7/8" tall. Text and inscription accented in white surrounded by a little brown color and we're not sure if this is brass luster loss or as made but everything displays distinctly. Likely a regional issue and certainly rare. First we've seen. Exc.
