Okay, I've hit the limits of my sanity on this one ... it looks so familiar but I can't place it. It seems kinda Zapfy to me, but maybe that's just because the verticals curve like Optima. It's not Michelangelo, Palatino, or Zapf Renaissance. Trajan and Goudy Trajan have a similar "feel", but don't match. Where have I seen that R before..? arrgh.
