Researching the 1926 New York International Philatelic Exhibition

Here's another video from Ken, one of our volunteers. Ken was researching the 1926 New York International Philatelic Exhibition and turned to our library for help. He found a catalog from the show that helped him produce the latest video on his TH-cam channel.
Ken presents an excerpt from that video, describing the show and the release of the White Plains souvenir sheet from the show.
