Novelty WWI Artillery Shell Photo Frame

Durch Kampf zum Sieg (through struggle to victory) artillery shell shaped photo frame with a WWI Iron cross on top. It is a little dirty but is still a striking frame. It has a studio portrait of an enlisted infantryman in Wehrmacht dress uniform. I am sure the frame is WWI, but the picture is obviously WWII. The photo was in the frame like this when I found it. It is made from metal.
