We present an art gallery theorem for simple polygons having n vertices in terms of the number, r, of reflex vertices and the number, c, of convex vertices (n=r+c). Tight combinatorial bounds have previously been shown when 0==5c-12. We give a lower bound construction that matches the @?n3@? sufficiency condition from the traditional art gallery theorem when @?c2@?=3.
