Photoshop unless Kennedy was a giant
According to the information provided at this site, about five foot, zero inches tall.
The light source for the picture and the figures' shadows is clearly to the left of the camera lens. Using JFK's headshadow as the standard, any figure to his right (to the left as the lens sees it) should have less of a shadow that would extend to the right of the figure, not more shadow on the right when viewed from the lens, as Nancy's does!
What Nancy has put forth as real is clearly a fake! (This time as well.)
