I'm pretty sure this photo was taken by Jan Newberry or Miya Ramsay, although I don't remember either of them having a Polaroid Land Camera. I have the original Polaroid, but no one has written on it. It was stapled to a postcard or something and mailed to me from San Francisco, according to the postmark. In 1982 I was living in Seattle, just after leaving NYC and Europe, and before moving to San Francisco. So, someone took the pic. in NYC, and mailed it to me from SF? That would make Jan the likely photographer.
When we lived in NYC, you could still see Keith Haring and Basquiat doing graffiti on the street and subways. Haring used to do chalk drawings several days a week on these black panels in Times Square Station, which I passed through on my way to my job in the village. I saw him a couple of times drawing with chalk on the wall. Had people realized those drawings would one day be worth tens of thousands of dollars, they would have probably removed the walls.
