Maya and Barack in San Francisco in the 1970s

In this screen shot of a frame around 1:59 in this video at the BarackObamadotcom Youtube channel, big brother Barry holds his sister Maya by the Golden Gate Bridge. I love this picture. Since Maya was born in August 1970, I'd guess this could be the summer of '72? I tried to restore my screenshot of the lo-res video of the faded photo to what I imagine the scene actually looked like. Despite some artifacts in the sky and under the bridge, I think this is about right.
The shirt was (Vietnam) camouflage green, not (Desert Storm) brown, as it appears in the reddened photo. I used to have one like it around the early 70s, shortly after I ruined the paisley one by forgetting some chewing gum in the pocket. Some green light reflected off the shirt onto Maya's arm, Barack's face, and the side of Maya's face. Young Barack's hair was more of a deep rich brown with reddish highlights in the bright sun, if these colors are right, and Maya's hair was a lighter brown with a reddish tinge, too. They are both squinting under a bright late-morning sun. I guess they are in a spot Golden Gate Park, facing south. I don't know the area well. It's a really nice snapshot of (the universal) brother and sister.
