To me this feels like the man is in deep thought or confused and they lady is taking more notice of the photographer. They are both dress well so this shows that they are not poor. It could be a husband and wife
I like this picture because i like the way she has a little smirk but the man is lost in concentration.
I Also like the way the photographer shoots in black and white
this gives the photograph a ofentic vintage look.
To me he looks like his job is very high-end as he is dressed like an aristocrat
She on the other hand looks a bit more middle class.
