Portraits In 1990 Rosenfeld produced a series of (mostly self-) portraits, some featuring the artist in a sunhat, and then as “sneaker man.” These black crayon/Aqua-tec and/or graphite works on paper, entitled among others, Blue Jew in a Sunhat - ½ imprisoned, ½ Imprisoned Man Drawing, Janet, Man in a Sunhat and Sneakers, Sneaker Man, ½ Finished Saint with a Pipe, and Laughing Running Shoe and Man, preceded—some finding their way into—his signature Crushed Spray Can series, executed in 1990–91.
