    American Perspectives on Heraldry and Vexillology
    Raven: A Journal of Vexillology 6 41-53. 1999.
    The world’s foremost vexillologist compares the sciences of heraldry and vexillology, through a review of civic symbolism in the United States and its manifestation on flags. He distinguishes it from European heraldry, and challenges heraldists to apply the same scientific principles as vexillology.
