The painting in the question is titled "City Night", a piece from a collection of more than twenty scenes showing New York City and its big skyscrapers. The painting shows a shining moon in between two huge architectural buildings, with their perfect straight lines of the building contrasting with the vast empty space of the sky. The painting depicts the presence of the modern era in its buildings, the minimalist presence of us humans amidst the huge structural architectures.
