The word BOO! sits alone at the center of a cream panel, its uneven, flared capitals filled with dense, chalky black crayon. A wobbly double rule outlines the panel, and a border of large, irregular black and cream squares runs off the edges of the picture.

The light is flat and matte, with no shadows or gloss. Grainy oil pastel and gouache, visible paper tooth and tiny cream speckles in the black fills give it a playful, hand-made folk-art poster feel.
