An elaborate heraldic-style bookplate in black ink on ivory paper, assumed to be that of Louis XV, King of France and of Navarre until 1774. If accurate, accompanying letter states it was sent to Helen Pearson from William P. Frost in April of 1945. Frost bought the bookplate from a collector in Paris and gifted it to Pearson. The image is an ornate shield emblazoned with scrollwork and topped with a crown. The shield rests on a cloak of ermine fur, with plants and banners on spear points behind it.
