This broken mirror at Dundraw shows both concave and convex reflections. It should be convex and the image is the right way up in that one. The sky is at the top. The broken bit is now concave and from a long distance beyond the focal point, the image is inverted - the sky is at the bottom. Below is the concave part from close up where the image is the right way up again. I must have been closer than the focal point.
