A print from the original negative of the image that was used by Trident studios for their brochure in 1968, featuring Paul McCartney and Mary Hopkin in the summer of '68

3 photographs were taken, 1) Paul looking to his left and smiling at Mary, a widely published image, 2) Paul slightly elevated looking down toward Mary and the control board, 3) this one, a more serious, business-like shot, this is the pic that Trident went with, it wasn't otherwise commercially released.
