Photo by Mrs.MessmanI took this photo when my students and I visited the Stevens Estate in North Andover. This door was part of one of the outbuildings on the property.  The dull, greenish gray color of the door really stood out against the brown wood frame and the red-orange bricks. There are so many types of lines competing for attention. The horizontal lines on the door itself are in the shape of rectangles, while the the lines on the brown door frame run vertical.
