The American Mural Project is a celebration of American ingenuity, productivity, and commitment to work. It seeks to inspire, to educate, to invite collaboration, and to reveal to people of all ages the many contributions they can make to American culture. It is intended as a tribute and a challenge. Launched in 2002 by artist Ellen Griesedieck, the American Mural Project (AMP) is creating the largest indoor collaborative artwork in the world—a mural 120 feet long, 48 feet high, and up to ten feet deep. The mural is a tribute to American workers and highlights what has defined the country over the last century. Nothing like it exists in the world. More than 15,000 children and adults have helped create pieces of the mural, and an additional 30,000 from all 50 states are expected to help finish the project. A multi-subject curriculum based on the mural is in use in several schools across the country, and an online version is in development.
