This is a stereo viewer card, a 19th century invention. Each card held two almost identical images that, when viewed through a stereoscope, created a realistic 3D scene. When viewed through the stereoscope’s lenses, each eye sees a slightly different perspective, and the brain merges these perspectives into a cohesive scene.
In this case, the scene is from a farm near Bamberg, Germany. Those are hop bines in the background.
