Nicely aged 1/32" copper roofing panel that is crimped on both edges. If the crimped edges were flattened you'd have a 24" wide sheet. One side is weathered. The "bottom" looks more like traditional copper. It may have a little dust/dirt or tar residue from being on a roof for forty plus years. Could make a great interior accent wall, use as wainscoting, or metal working projects--if you're not ready to put on a copper roof. Dimensions are approximate. Weighs ~1 pound per square foot.
