I'm Carlos, an artist in DC who collects stamps, draws cities, and spends too much time in archives. My newsletter is where I share the things I find along the way — a 1940s tram pass with racist propaganda next to a holiday greeting, a mural in St. Paul that changed how I think about walls, a curious fact about France's longest border. It goes out every other Wednesday. It's free. And it comes with exclusive deals on my prints.
