That tree on the flag at the top looks like the one used by the Citizens Party (USA) in the 70s/80s. I tried to find a pic, but DuckDuck is all over my search thingy and Google won’t let me in, even when I make them the default. So I found a box with a file, and one small B&W of that tree, over the words CITIZENS PARTY. Too much trouble to scan & share. It looks just like the one at the top, except all black. With different words.

The Citizens Party was to the left of the Democrats, but not very much. I was at their convention in San Francisco, and I remember a woman at a meeting talking about the youthful left fringe of the group, and how they could be used. I was disgusted, but as a youthful person to her left, I kept my mouth shut. I did too much of that.
