A short article describing a sixteenth-century cover of filet (réseuil) and cutwork, with reticello squares, owned by Mrs. Albert Blum. It compares the designs to patterns in Frederic Vinciolo's 1587 pattern book and discusses the heraldic and royal emblems in the reticello squares (double-headed eagle, globe, fleur de lys, monograms), linking them speculatively to Philip II of Spain and Elizabeth of Valois. Photographs show the whole cover and details.
