Artist Buckley Mac-Gurrin, an art critic for the literary film magazine "Script" published by writer and artist Rob Wagner, wrote in a cover story of Politi in 1940 that "Leo became proficient in the use of many media – oil, watercolor, wood-carving, wood engraving, lithography, book illustration; he had a very fine artistic education. His training was modern as opposed to academic; it tended to develop originality rather than subservient to the art forms of bygone eras. His own artistic philosophy drew him toward the genuine and the earthy; toward people whose contact with the soil was still fresh, intimate, satisfying."
