You can see part of the triple observation towers of the New York State Pavilion, designed by architect Philip Johnson for this World's Fair, peaking out from behind the metal post on the right of the shot. (Those of you who have seen "Men in Black" must remember the part they played in that film)
My mother is in the orange dress and I have the red headband on. That is one of her boyfriends and his son. This was right around the time of her separation from my father. I remember this day vividly.
It is funny how you can see things so differently as you grow and mature.
