Rivet wall at the Harley-Davidson Museum in Milwaukee, Wisconsin. The stainless steel rivets, engraved with a custom message or personal tribute and donor name are attached to a weathered, rusted wall.
According to Harley-Davidson, each rivet tells a story and you can listen to some of them here.
The rivet wall currently consists of two curved sections and will grow significantly in the future.
