There's a movie in theaters right now called The Current War that brings the Westinghouse/Edison feud to life. Unfortunately, Tesla has only a minor role in the movie. Through the magic of special effects, they bring the Columbian Expo to life near the end of the movie.
Speaking of Columbian Expo stuff and giveaway swag, though I no longer have a ticket to the Expostion to give away like I did in that old 2017 contest, I just launched the November 2019 giveaway, and Prize #1 in that contest is a "pick your own" option. There happens to be a decent Columbian Expo half as one of the prizes in that pick bin, as of this typing (. If anyone wants to join the current giveaway for a shot at that coin (or dozens of others), you may do so here.
