When it comes to artistic ideals of female perfection, some examples leap readily to mind: Botticelli's Venus; Shakespeare's Portia; Marcia Brady.

McCormick (who still looks amazing, by the way) will be signing copies of her new tell-all, Here's The Story: Surviving Marcia Brady and Finding My True Voice. Tue., Oct. 21, 7 p.m., 2008
