7. Doors, NYC

As we recently covered, Roy Colmer photographed 3,200 Manhattan doors in 1976 in his conceptual art piece Doors, NYC. To execute the project, from November 1975 to September 1976, he took pictures of doors that he often saw everyday in sequence. This meant that he left out doors from entire neighborhoods, which is why the photographs on the map are somewhat clustered. According to Vanishing NY, Colmer did not care about “the particular street, historic or architectural importance of the door.” Instead, he just took pictures of whatever doors he immediately saw as he walked.
