Great picture. What is also interesting (and relevant to someone who lived in New York in 80s and 90s) is that the window has been left open. Many people left their windows open back then to prevent thieves from smashing the window to look for a radio or other valuables (especially if you didn't have a radio or other valuables). Also ubiquitous were the "NO RADIO" stickers people put on there windows (even if they had a radio, in an attempt to ward off potential thieves).
