The first one is authentic. However, the seller in the link you posted did not use her own pictures. She had previously bought this bag from this seller (who is a reputable seller):
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=350204216081
and copied that seller's pictures and description. (I can't recommend buying from a seller who copies someone else's pictures and description.)
This bag is from the Polka Dot line that came out a few years ago. It's a really cute style. I had the demi. There is a creed inside the satchel and there's also a hangtag on the outside as you can see in the original seller's pictures.
The third bag is the Valentine's Day Scarf Print that came out for this past Valentine's Day. It's absolutely real.
In the future, please post here if you're questioning authenticity:

And remember, just because you haven't seen a style before, doesn't mean it's fake!
