Mysteries of the Unknown

There was "Mysteries at the Museum" and now "Mysteries of the Unknown". Different names, same format. I found the original series interesting, but also noted "inaccuracies" in some of the offered segments that I had some familiarity with. An "oddity" from a WW-II segment in the earlier series has stuck in my mind. It's a picture of a group of helmeted soldiers aiming flintlock rifles. Whatta hoot. I assume the series developers inserted that "Easter Egg" picture as a joke. I DO find the episodes interesting and enjoyable to watch most of the time.
