Acclaimed writer and Pulitzer Prize winner Katherine Anne Porter was honored today by the U.S. Postal Service with the issuance of a commemorative postage stamp. Considered a master prose stylist, Porter taught at many prestigious universities, despite never graduating high school. A first-day-of-issue ceremony was held at the Katherine Anne Porter Literary Center in Kyle, TX. The new stamp is only available in Kyle today and at Post Offices and philatelic centers across the nation tomorrow.
