American Philatelic Society and National Postal Museum
In October 2020, the American Philatelic Society, American Philatelic Research Library and National Postal Museum, with the USPCS as a partner, sponsored a week-long series of virtual talks on “Postal Innovation of the Classic Era”. They have hosted those talks on YouTube and made them available to us. We are pleased to be able to include links to these talks here. You can also find them on the APS website at https://stamps.org/postal-history-symposium
