Found this gorgeous art deco motorcycle pic and was keen to learn more.
It turns out the story of Henderson burns brightly and quickly...
...In 1911 the Henderson Motorcycle Company was founded in Detroit Michigan.
It produced 4 cylinder motorcycles for local and overseas markets, including New Zealand. They were the largest and fastest motorcycles of their time, and appealed to sport riders and police departments. In 1931 the company owner chose to end the motorcycle side of the business and concentrate on bicycle manufacture. Without prior warning, he gathered his staff together and bluntly told them, “Gentlemen, today we stop.”
Well, that’s the bad news... the good news: I now know what I want for Christmas.
