Chester County Historical Society Philatelic Lecture Series Archive
From December 2017 through April 2018, the Chester County Historical Society held a seminal Philatelic Lecture Series called “You’ve Got Mail” in West Chester, PA. This was made possible by our friend Bill Schultz, longtime Exhibitor, Accredited APS Judge and Board member of the American Association of Philatelic Exhibitors. Admission was free for all lecture attendees and all lectures were underwritten by generous donations from the philatelic community.
The speakers, preeminent philatelists, postal historians and award-winning exhibitors, are listed in the CCHS Lecture Series Handout. We are immensely grateful to the speakers who kindly permitted us to share their presentation on our website. Please note the contents remain the property of the author.
