In the C/E train station at Spring St, on the uptown side, on the wall of the stairway landing, is a mosaic mural, “Subway Station,” created by Edith Kramer in 1994, which features the 14th St.-Union Square station. At the work’s base a candle burned all last week next to some flowers, while a pair of photos in a plastic frame were perched atop a book, “The Artist’s Handbook of Materials and Techniques.” Kramer, who died a few weeks ago at age 98, was a social realist painter and a follower of psychoanalytic theory who arrived here in 1938 from Austria as a refugee. She went on to teach at the Little Red School House and was a pioneer in art therapy, founding the graduate program at New York University. Over the past 20 years, her mosaic public-art piece has lent artistic flair to the otherwise drab subway stairs at Spring St.
