I usually don't pay that much attention to titles and focus on the image, but have to say I love your title and that is how I often feel when taking street photos of persons I do not know - they are the unknown people - I capture their image and because of that I have some connection to them - but they are the "unknown" and will always remain unknown to me. Is there any truth in the image? Anyway Yiannis this is a lovely, sensitive portrait...
that was my first thought too - he looks more fragile than the dolls in the bottom image and yet in the top image to me he looks very strong. i like this double portrait.
