Google twice, actually. I'm often intrigued by the things that appear when searching google images; in yesterday's case, my search for "beam jockey." I'm really curious about the source of that image -- it looks rather like an old postcard or perhaps horse racing memorabilia, but the page I found it on was part of the encyclopedia of science (http://www.daviddarling.info/encyclopedia/M/mass.html
) and it didn't mention the image's source. Google was unable to locate any other copies of the jockey being weighed, so it seems I'm going to be forever curious.
