WW2 Plaque Army Ludwigsburg

This is a very interesting handmade piece of someone's military history. It is a 4 1/4" square piece of wood, beveled and decorated with a burned-in design all around the edges. At the top corner there is a piece of wire, now showing its age, twisted to make three loops (one to hang it by) and fastened into the wood. At the top of the plaque itself, there is a 7-point star. At the bottom is this: 7th Corps. In the center there is a medal or rank bar, and on one side of it is "U.S." and on the other, "Army". At the bottom is a shield design with a banner underneath. The words "13th" and "F.O.B." are on either side of the shield. Along the bottom left side of the plaque is "Ludwigsburg," and on the other, "Germany". at the very bottom corner is the date 1945. The star, bar, and shield are colored, and all the design outlines and words are burned into the wood. The plaque appears to have been displayed on a wall, rather than stored away. It is 4" square and 7/16" thick.
