Answer:
Those alleged nude photos are misleadingly attributed to Ann Dunhum, Obama's mother. An unauthentic Aussie blog site claims to have discovered Ann Dunham's nude photos but those photos obviously show that the model in those nude photos is just a look-alike of Ann Dunham and even the original poster of those photos is not sure about authenticity at all. The Aussie blogger claims to have received the following e-mail(below) with three attached nude photos but the Australian source completely lacks credibility. Moreover, the series ID number of the vintage photo is YA-438, which does not match Obama's mother's initial A.H., which proves that the model is not Ann Dunhum. Any photos from the vintage porn site carry models' initials in the lower right of photos.
"By pure serendipity I found a photo of what I believe is Stanley Ann Dunham; two more I found through sheer plod. They are taken before Christmas by the decorations and unopened presents. Also a stereo and records that an expert could confirm as jazz records are in view.There is a distinctive grain to the wood floors. I do research including genealogical and had downloaded everything I could find. Not much. So when I saw the picture, I locked on the the ear lobes, chin, eyebrows. It is she. A nude photo, not distasteful, but posed, I believe, by a mature man who knows what he likes, including jazz and now we know young girls. One could ascertain the location of where the photos were taken. And the shoes..not indigenous to Hawaii, but maybe not unsual for Helen Canfield Chicago socialite and Marshall's second wife. The photos are important in the sense that they explain the going to Chicago and the immediate acceptance by the hard left, if his father is Frank Marshall Davis, not just his mentor."
