The NY Times highlights a largely unknown Keith Haring mural in a convent stairwell on the Upper West Side.

Mr. Haring painted it on a Saturday night in March of 1983 or 1984. More than 50 kids were staying at Grace House for a retreat, and a handful watched Mr. Haring work. In all, it took less than an hour and a half.

“It was mesmerizing to watch him, and for me, I was very proud of having him there doing that,” said Mr. Soto, who is now a party promoter. “I felt like it was for us.”

Kinah Ventura, another member of Grace House, remembers the night vividly. “For kids who were into graffiti,” she said, “it was a different spin on what art is and what art is about, especially because he was so positive.”

Pretty cool. Hopefully they can cash in before a band of art thieves attempts to rip the wall out.
