One original 35 mm black and white negative taken by a Dallas Times Herald staff photographer. The image shows a doctor speaking with Dallas Police officers in a hallway at Parkland Hospital after the arrival of Lee Harvey Oswald on Sunday, November 24, 1963.Although the pictures on this negative strip have been attributed to photographer Andy Hanson in the past, curators have concluded that it is not possible at this time to say with any certainty who took them.
