This one has been posted and captioned as Ann, 18. So she would have been pregnant with Obama here. If Maya was really 9 years old in 1972, then Obama would have been born in 1954. So this picture at the airport may be circa 1954.
One reason I think the Honolulu air travel line of inquiry could be worthwhile is because people DO take arrival and departure photos when going on exotic travels. In the sixties Hawaii was still exotic. I don't have any pictures of the terminals (mine seem to mainly consist of geckos mating outside my hotel, and some scuba shots), but perhaps other Freepers do.
We are looking to see what the inside of the terminals looked like year-by-year, from 1958 through maybe 1975. Any photos appreciated. Also of San Fran.
Then we can more accurately date the Obama family photos.
