After a closer examination, I still maintain that all three images are of the same person.

I'll accept that picture three is the same person as person one with age progression and makeup. But take a look at the cheek bone structure in picture two. Nose is somewhat different.
With a good theatrical quality make-up kit, I could change the person in pictures one and two into the person in picture two. But if these were all casual pictures, not a covert op, or some other unusual effort at changing appearence, I'd say person two is a different person.
Sorry, I no longer have access to a biometric or Bertillion-type photo analysis program. But I'd guess picture two is somebody else.

angusniagara has good point...
 

about the nose that I hadn't noticed before.

In the second pic, the nose is different from the nose of picture one and three. The nose of the second pic girl has a little bit of a flat pushed up nose whereas the nose in picture one and three is rounded full-bodied nose there isn't a flat part to it at all on the tip.

I hope this makes sense to most of you...if I can think of a better way to explain this, I will edit later.

New photographs and metadata extracted
 

Hey all, good response so far. Some of you are paying a lot of attention to this!:)

In response to at least 2 claims that known1.jpeg and known2.jpeg are not the same person. I must acknowledge that after reviewing my sources, it is possible that 'known2' may indeed not be the same person as 'known1'.

I have submitted two other photographs for examination, I do however insist the veracity of these are almost beyond reproach. Both are posed shots.

known3 was almost certainly taken in the last 12 months. The image is thumbnail sized and there is no better resolution available.

known4 is from around 2004, is most likely a scanned copy of a printed photograph.

Both are most recent than 'known1' - so if you have to discount a photographs. I'd rather discount known1 in favor of these two new photographs. The age difference in subject between known1 and mysterywoman could lead to incorrect conclusion.

Its not much to work with, but can you folks compare these against mysterywoman please.

I also have another piece of information in the metadata of the mysterywoman file. The original photograph was taken using a 'Concord 2000' camera made by Concord corporation. Is this a make of camera found exclusively in one region of the world? Of course, cameras can be transported internationally too...

New photo, new details and yet no replies.

I stand by my initial promise to post a photo of her with her box fully open, if I can get 15 unique responses.

Looks the same to me
 

She is wearing makeup in the 2nd pic, and you can't see her ears, but the nose seems to look similar.

Because the lighting, camera quality and stuff is off, hard to be sure

all are of same girl !!

Looks like the same girl to me.

I find it entirely plausible, given the change in lighting, that they could all three be the same person.

Definitely 3 different women.
