Publicity photo of Nikola Tesla in his laboratory in Colorado Springs circa 1900.
The laboratory was built in 1899. Tesla sent a copy of this photograph to Sir William Crookes in England in 1901.
This image is a Double exposure. See [1] (http://www.ttr.com/model9_page2.htm) for more modern examples of the same technique with a contrasting photo of what a large tesla coil arc looks like in a single exposure.
The photo is cited as a double exposure by Carl Willis and Marc Seifer.
Tesla's Colorado Springs notes identify the photo as a double exposure.
- To give an idea of the magnitude of the discharge the experimenter is sitting slightly behind the "extra coil". I did not like this idea but some people find such photographs interesting. Of course, the discharge was not playing when the experimenter was photographed, as might be imagined!
This photograph was taken in the USA prior to 1924 and so would be in the public domain.

Conversely a copy of the original photograph was collected by Leland I. Anderson who sold the collection to Tesla Wardenclyffe Project (http://www.teslascience.org/archive/archive.htm). They now claim copyright. Note that the version in that archive includes a hand written note added in 1901 printing which doesn't appear on the more widely available image.
