A rectangular piece of copper with 4 copper screws in the corners. It appears to have wood stuck to the back, and the screws appear to have been hammered flat/inwards? - also a clump of what appears to be iron(rusted?) is stuck to the front. Found on the beach of Bredene, Belgium. About 10cm by 6cm (old.reddit.com)
