Announcing Poly Crepe de Chine!
The descriptive phrase for this technique, "trompe l'oeil" (which means to deceive the eye) dates from the Baroque, but the technique - often seen in murals - was used from Greek and Roman times on. Typical examples use a window, door, or hallway to suggest larger spaces (more information here).
Original version. Line art & stencils, half-brick repeat.
