In this photo President of the United States, Lyndon Johnson is sitting between Dean Rusk and Robert McNamara in a Cabinet Room Meeting in February of 1968. Of course, President Johnson is wearing his trademark Rolex Day-date in Yellow Gold.
I am working on a Definitive Rolex Series on the History of American Presidents wearing Rolex watches, which will be fascinating. Lyndon Johnson wore Rolex Watches for decades.
