Nighthawks by Edward Hopper 1942. It is an oil on canvas. I chose this art work because I've seen this before and I just love the era that it is in. They way how things were back then, how the people dressed and acted. Even the way he used the colors in his art work. The colors outside the diner represent dullness so you can assume it is dark outside. Hopper with this work painted scene's mainly at right angles. I just really enjoy this painting.
