According to United States Stamps 1922-26 by Gary Griffith, noted dealer Philip Ward purchased a pane in 1925 in Oklahoma. Part of the pane was marked for destruction by blue crayon, but apparently made it into circulation. A second pane is also known, which was similarly marked for destruction. Examples without the blue crayon are rarer and more desirable.
