Black flag with coat of arms of the De Graeff and Herzeele families

Black flag with an eccentric white rectangle on the breeches side, with the coats of arms of Gerrit de Graeff, and Christina van Herzeele, brought together under a helmet in blue with ochre against red foliage. Above it a crown with five points: three with fleurons, two with pearls, alternating, and above the middle one an upright trowel with ochre-colored stem and blue scoop. On either side of the coats of arms a swan that sticks its head into the red foliage. All this stands on an asymmetric foot with foliage. Below it a scroll in gold, on which in black classical capitals: MORS, SCEPTRA, LIGONIBUS, AEQUAT. Along the breeches a band of truncated triangles in black and white. At the top and bottom black-white fringe. Eight sets of renewed ribbons on the breeches.
