MSN

Sometimes, the internet is just no help whatsoever.  I was fairly certain that wasn't an American uniform seen in the top photo, so I blew it up as large as I could.  The insignia on the man's collar, an anchor and the letters MSN.  Needless to say, type MSN into a search engine and all you get is Microsoft.

So with the Asian hostesses, these were probably taken somewhere in the far east, so maybe Japan, the Philippines, or even Vietnam.
