This site is a great use of art to teach history. It chronicles the career and work of artists working with Native Americans in the Pacific northwest around 1900-1910, showing the images and telling some of the stories of the native people who lived in the area. The artwork includes paintings, engravings, and photos of an aspect of Native American culture that is often overlooked. Great site for research reports, class discussions, and the like. The texts include pictures and maps.
Subject matter varies, and publication appears to be sporadic.
Still, it's a nice collection of different materials. The trading post, though, is mostly a convenient meeting point for native and western cultures. There are some striking images and powerful text here. The Boston Children's Museum developed this site to help children learn about a Native American tribe that is native to Cape Cod, and which remains active today. The site includes both historical information and a look at how tribe members live and maintain their heritage today.
