One of my favorites is this video, "About Bananas," which is a silent black&white film about, well, bananas. See here: https://archive.org/details/AboutBan1935
Banana export was St. Lucia's largest source of income until recently, when shifts away from St. Lucia in the international trade put local banana growers out of work. Instead of being able to make a living on their land with their family, many Lucians now have to commute to work at the island's many tourist resorts, resulting in time away from home, money spent on transportation, children being left unsupervised, etc. This is one example of a riff that history has torn through St. Lucia and something we're going to work very carefully--with the help of archive footage--to visually explain.
