Winslow Homer (February 24, 1836 – September 29, 1910) painted landscapes and made prints. Often he used his working vacations to produce new art in either oil paint or in watercolors. Eventually, he was employed as a commercial illustrator for popular magazines. Homer studied art on his own, and he developed new skills and techniques.

Remember, Picture Study is very simple. Show one picture to your children. Let them look at it carefully for a few minutes. Then, put it away and talk about what you noticed in the art. What colors did you see? How many people are there? What are they doing? What kinds of buildings are in the pictures? What kind of landscape? Are people having a good time? You can always check the picture to settle disagreements or to refresh memories. Chase rabbit trails where you can. When the conversation dwindles, move on to another activity.
