This one I have had a long time, Bedford Co. Pa. The way it looks here it is about 3 inches high. 1.5 wide and 1/4 think. There seems to be a seam along the edge and there is a small image of a brachiopod on the side. On the right lower half it looks like a flap coming up over the middle part. I have always called it my bean pod. I would love to know what this is.
