Copper plated wall plaque

Large, heavy, solid copper-plated wall plaque, measuring 120cmx43cm and weighing 15kg. The relief scene depicts a horse drawn log cart, with a gentleman resting beneath a tree with what appears to be a saint/Madonna shrine on the tree trunk. The scene appears to be of Germanic origin, possibly dating from 1920's onwards, as the cart appears to have pneumatic tyres.

There doesn't appear to be a maker's or artist's name anywhere on the plaque.
