this one's a crap shoot -- no stats on the ad, and no clues as to track record mean that she doesn't want to b identified from the information she is giving you.  that could be for any reason you choose to imagine, but it prob ably meanss that the pics are not very representative either.  so your only choice is to call and see if she will give you review info over the phone, and ask some questions to see if you can figure out the other things you need to know.  For example, "The pics are blurry.  Are they a pretty good likeness of you? "  And then you're listening to see whether   they are her or just somewhat like her.  And then ask her what she means by GFE.  And then roll the dice.  But without the reviews, no stats, two names, and with these pics, and only in town for two days, I would bet your $$$  this is bait and switch shoot and scoot.
