These are just a few photos of women (Japanese and Filipina) and some native Islanders in what I believe to be the Philippines.  My Grandmother used to call these Grandpas WWII girlfriends.  One of the photos has the name of the girl written on the back.  So Grandpa Les must have known her in some capacity.  Girlfriend.  Customer.  Who knows.  Maybe he almost married one of the girls he met in post-war Japan.  Thousands of GIs did so in the years between the end of the war and today.
