I think what also matters in this thread is having fun and I just wanted to give other people an opportunity to have some fun too ;)
Whose head is it?
St. Wojciech (Saint Adalbert of Prague)? He's the patron saint of Poland.
What is this woman`s job?
Street merchant selling fruit - in this version she's selling oranges (there's another painting in which she's selling lemons). This painting is well known because of it's history - it was stolen by the Nazis from the National Museum in Warsaw during World War II and recovered by Poland only in 2011 (I like Gierymski's paintings, btw):
