Thanks for your input.    While on a overnight stop in Fort Myers I saw this ad in BP and the pictures were too good to be true.    When I did the reverse image search, the photos turned out to be of a model for spa and spa products in Czech Republic.

I contacted the lady using them and she appologized and claimed it was her husband that put them up for her advertisement.  She removed them promptly!  
Watermarking is a good thing!!
