Fairfield Porter's painting

I like this painting from Fairfield Porter, because he didn't draw too much details, not like other artists focus on character's emotions, clothes and actions. He used really simple way to show what he was thinking. All figures without face emotion, but audiences still can feel and understand what he was drawing and what kind of message he wanted to pass. We can see there is a tennis double match, and one boy serves, two boys whose backs face us are nervous from their poses. Fairfield Porter's painting is special and interesting.
