Perspective, with the Reason of Shadows and Mirrors

A rectangular dark panel, likely a leather book binding or a printed plate, is centered on a background of marbled paper with a "combed" or "peacock" pattern. In the center of the dark panel is a heraldic coat of arms. The shield is divided horizontally (fess); the upper section contains two five-pointed stars, and the lower section contains a crescent moon. The shield is surmounted by a decorative helm with elaborate mantling of acanthus-style leaves. In the four corners of the dark rectangular panel, the initials "IB" are printed or embossed in a serif typeface, oriented to face the center.
