Ventilation grates for the Archer Avenue Line subway at the southeast corner of Jamaica Avenue and 149th Street in Jamaica, Queens. The grates along the line are interesting for various reasons, including the fact that they often are lined up south-to-north, stretching north of the actual subway line.
