Photos on social media are so numerous that it's easy to forget that there was ever a time when humans didn't have the benefit of photography.
These photos, and their stories, were all found on Reddit, and date from the 19th century to just a few decades ago. They are each fascinating in their own right and also form a direct continuum to the modern-day photographers of Instagram.
