 He also enjoyed the work of James Rosenquist, whose work was more about surface than substance; however, Green's objects appear to have a psychological rather than just a visual presence.The imagery Green has used throughout his entire career, and continues to use to this day, is drawn from illustrated textbooks and advertising of the forties and fifties that touch on technological and roadside Americana, with overt themes of sexual symbolism.Imagery includes ice cream cones, bridges, incomplete bridges, mirrors, scissors, women's painted fingernails, passionate couples, tires, moons floating over water, puzzle pieces, silhouettes of a plane flying overhead, searchlights, tornados, women's nylon-covered legs, wood grain, leather cords, screws, cables, knots, zippers, tapes, stitches, Necker cubes, and other optical illusions.
