Mirror, trapezoidal in shape. 26 inches high, 47 inch base and 26 inches across the top (can, of course, be flipped). This mirrors unusual shape makes it very interesting. It was removed from a rear projection television and has the clearest and brightest reflection of any mirror that I have ever seen. It is fairly thin, with rounded edges (that won't cut you) and light weight so it could be hung directly on the wall or you could frame it.
