This is one of Charlotte Johnson's most famous paintings: The Subway NYC 1994. During the 1980s and 1990s she was married to the wonderful Nick Wahl, a professor at NYU. It was the greatest tragedy that he died in 1996 aged 68, obviously a tragedy for Charlotte but also he was a wonderfully sane, wise voice, greatly respected and admired by his step-children, and he would have made a difference to this country and the disaster that has overtaken it by helping Charlotte make wiser decisions about her relationship with her eldest son. Brexit might not have happened if Nick Wahl had lived.
