I have only recently came to the conclusion that an American is Barack's father. I had known about the pictures for a couple of years, but I had never considered that they might be connected to his conception. After listening to some of my so called conservative allies ridicule "birthers" (such as myself) and proclaim the issue "Over" , I decided to rethink the available evidence. I decided to try and date the pictures to see if it would give me a clue, and after an internet search, I recognized that album "Cuban Fire" by Stan Kenton. The first website I went to said it was released in 1960, (Later shown to be wrong) and therefore I concluded the pictures must have been taken in December 1960, Shortly after Barack's conception.
All the random bits of data "clicked" in my mind, and I realized this was the answer. I then set out to try and explain it to others. Nothing seemed to work. The First response I always got was "Naked Pictures! What kind of sicko are you? "
I decided the only way to get past the initial visceral reaction was to get people to admit obvious details about the pictures before they understood that they were doing an objective analysis. Then, when I later showed them the whole thing, they couldn't deny what they had already admitted. This worked on another website (for some) so I thought I would try it here.
If I look as though I came "out of the blue" that's because I did. I've lurked around here off and on for a year or so, but I only recently joined because I perceived that my interest in this subject was shared by others on this website more so than elsewhere. And as I mentioned above, I only recently came to the "American father" conclusion. (A little over a week ago.)
As to your points on paternity and the claim that Muslims don't celebrate Christmas: Have you firmly established that this is a room in FMD's house?
I have not, but I have traded emails with someone that implies that he has evidence of this. (I'll send a PM)
If so, how did you acquire that proof?
I don't have any proof that it is. I merely point out that it is not likely to be Barack Obama Sr's room. It is the room of an unnamed American.
Can you show us photos of that same room and furniture at another date when he resided there?
No, but I am told that there are other photographs taken by Frank Davis of Nudes. It was apparently one of his hobbies. When I asked about the whereabouts of other photos, I received no response. (Not unusual from I'll send a PM) The "Vintage Pron" website appears to have been rolled over and no longer contains this content.
Who else have we ever seen in that room? What is the address of that house? Can we validate the dates he lived there? Did he live there by himself? Could someone else who lived there have been celebrating Christmas?
The Answers to the above is possibly. I am pretty sure I have seen the Address of Frank Davis listed. I don't live in Hawaii, so I don't know if it's still there or not. Someone *IN* Hawaii could probably find out if that room still exists.
Perhaps Google street view? I'll look into that.
Next: Why do you personally believe the person is SAD?
Apart from the obvious resemblance, the woman in the picture has a crooked upper left tooth in the exact same spot as Stanley Ann. (Enlarge the images and look at her upper left front teeth.) Then Compare them to this picture. 
It's too great a stretch of credulity to argue two women would look alike AND have a crooked tooth in the same spot.
Whose word are you taking that the images have not been manipulated?
I've looked at them under enlargement. There is no indication of manipulation, and what would be the motive?
If you haven't seen the originals, where do you think they came from?
They came from Frank Marshall Davis's collection of Nude Photographs that he traded with other collectors in the early to mid eighties. As I mentioned, According to researcher (I'll send you a PM), Davis had a hobby of photographing nudes.
Let's pick it up from there if you want to continue.
I answered your questions to the best of my knowledge. I may find some more answers as time goes by, and you've given me an idea for one or possibly two new leads.
Good enough?
