r/MarkTwain

Mark Twain is holding one of Tesla's experimental vacuum lamps during a visit to the inventor's New York laboratory. The lamp was illuminated by Tesla's high-frequency apparatus without a conventional wired connection to the power source. Tesla is the barely visible figure at the left. The photograph appeared with T. C. Martin's article “Tesla's Oscillator and Other Inventions” in *The Century Magazine* in 1895.

As a huge Mark Twain fan, I couldn't pass this up. It's in remarkable condition for its age, plus it was only $5.
