Manhole Cover Bamboo Scarf, Detroit Tire Print Pashmina. These 300lb cast iron behemoths we drive over every day are often adorned with beautiful imagery, and are perfect for prints on long, fringed scarves! We make these by applying printing ink directly to the metal, with a reverse print as the result. While we don't know the date of this particular cover, we love the auto industry/tire and wheel reference, and bet you will too.
