Coastal Map of Cape Cod Massachusetts Lighthouses Wall Plaque Art by Melissa Hyatt LLC. Proudly made in the USA, all of our wall plaques start off as high quality lithograph prints that are then mounted on durable MDF wood. Each piece is hand finished and comes with a fresh layer of foil on the sides to give it a crisp clean look. It arrives ready to hang with no installation required, and comes with sturdy clear corners to keep it from damaging in transit.
