В тексте это объясняется сразу же за этим 51X, название галереи:

... appartment above 51X, a gallery in New York which was famous for displaying many graffiti works. Artists used the apartment to relax in when they were visiting the gallery, and between 1979 and 1983 it was traditional to tag the door.
