Awesome photograph! That’s Lyndon B. Johnson, of course, the 36th President of the United States, and I believe the child is one of his grandchildren. The puppies in the basket were sired by Him, which was the name of LBJ’s dog. (He also had a female dog named Her).
I believe the photo was taken on January 5, 1966. At the time this picture was taken, Johnson had just committed tens of thousands of U.S. troops to the war in Vietnam, and the war was beginning to take a heavy toll on both policymakers and American families alike. Despite the burdens of the presidency, however, LBJ could take time out to pose for cool photos like this.
Thanks to the LBJ Library for the original picture, which is in the public domain.
