The permanent collection of the (US) National Veterans Art Museum in Chicago contains more than 2,500 pieces of art by 250 artists, all of which can be seen at NVAM Collection Online. The site includes biographical material on the artists who created the work. Featured Artwork. A small selection. (Via. Images at links in this post may be nsfw, and/or disturbing to some viewers.)
The Warrior Writers Project brings together recent veterans and current service members to be in creative community and utilize art-making processes to express themselves. There is a deep necessity for veterans to create when so much has been shattered and stolen. A profound sense of hope comes from the ability to rebuild and transform.
Speaking of Veterans Day, here in Chicago we have the National Vietnam Veterans Art Museum. Art by Vets about the War. Most pieces are on-line with a short essay. The Above and Beyond memorial is impressive to say the least.
