This week, Deep In Bear Country goes deeper than usual into the wild world of Berenstain Bears ephemera with our guest, Mark O’Brien of the YouTube channel “Uncommon Ephemera!” He’s unearthed a Filmstrip interview/documentary about Stan and Jan Berenstain that is one of the most delightful things I’ve ever seen. I also have on, as a bonus, my collectors Brad Mariska and Jeremy Gloff to talk about the Filmstrip and just shoot the breeze. It’s fun!
