Harvey Dinnerstein (born 1928) has been able to carve out a long, New York based painting career without ever compromising his devotion to realism (for a little background on this, click here).
Many of his subjects related to New York City, though there are exceptions. Matthew Innis discusses one, "Parade," at length here.
A 2008 book about Dinnerstein and his art can sometimes be found in bookstores and might be available here.
I respect Dinnerstein's courage and tenacity in not following the New York art market herd. However, I've yet to encounter any of his paintings directly, so will not offer commentary at this time.
