A Smithsonian documentary series featuring colorized footage of old home movies and rare newsreels. Can be watched at that link but not suitable for capturing vehicles for the site. Could be worth listing if only for the footage of the WWI-era tanks on the streets of DC to disperse the Bonus Army.
Taking a couple weeks off work to care for my wife while she recuperates from some outpatient surgery. I've bought this series and some automotive historic fiction from Amazon, will probably add images in the coming weeks.
