Sim, é possível. Extraído de esta discussão dos Grupos do Google :
Click on someone's people/face album. You'll see thumbs for all the photos that have that person in them. Click the People" button, lower right. The People tab shows other people appearing in the same set of photos. Click on another person in the "People" tab. That person lights up blue. And the number of displayed thumbnails shrinks to only the photos with those two people. Do a Ctrl-click on another person... now you'll see only photos with all three people in them...
