Shahn mixed different genres of art. His body of art is distinctive for its lack of traditional landscapes, still lifes, and portraits. Shahn used both expressive and precise visual languages, which he united through the consistency of his authoritative line. His background in lithography contributed to his devotion to detail Shahn is also noted for his use of unique symbolism, which is often compared to the imagery in Paul Klee's drawings. While Shahn's "love for exactitude" is apparent in his graphics, so too is his creativity. In fact, many of his paintings are inventive adaptations of his photography.
