Stenciling is a technique used for reproducing letters, images, or designs by applying ink or paint to a stencil, a piece of cardboard or metal with holes cut out in various shapes. The ink that goes through onto the surface creates the desired letters or shapes. Stencils can reproduce patterns quickly and easily, so they are often used for street signs and graffiti. The lettering on these covers uses stencil or mimics its style, alluding to modern urban life. Stencil contrasts with the use of handwriting on other covers.
