The recipe is the style, not the picture. Put your own subject in and the highlighted part of the prompt changes.
A 1930s Works Progress Administration national park poster, screen printed in five flat colours on rough board. A canyon reduced to four layered silhouettes with no outlines, a muted earthy palette of sage, ochre, rust and cream, a small silhouetted figure at the rim for scale. Short instructive type in plain capitals at the base. Slight misregistration, ink sitting visibly on the board, worn corners.
