Help needed finding a JFK photograph - sorry in advance!

Hi all, I hate to ask, but I'm researching JFK's assassination and it would be spiffing if I could get hold of this photograph in the highest resolution possible. I'm doing some analysis in Photoshop and obviously the higher the res, the better

Any help would be very much appreciated, and I apologise for intruding
