The flag represents the design present on the William Penn Coat of Arms depicted on a 2x3 flag with a blue and yellow stripe. The black stripe in the center spans the whole flag and is half of the height of the whole flag. Each white circle is a third of the height of the whole flag and spaced evenly apart. The blue stripe spanning the top and yellow stripe spanning the bottom the are each a sixth of the height of the flag and each white stripe separating them from the black stripe is a twelfth of the height of the flag or half of the blue and yellow stripe.  This design was created as a proposal to change the PA State Flag.
