Leslie Jones photographed a worker changing a lock  at the Brink's warehouse in the North End following the $2.7-million robbery on Jan. 17, 1950. It turned out that part of the gang's two years of preparation involved secretly replacing several locks at the warehouse beforehand to make their entry easier.
The warehouse still stands today, as a parking garage at 600 Commercial St.
