Army of Sandcrawlers!
This photograph of a female photographer during what we think to be World War II (not confirmed) gives us a glimpse of what is unmistakeabley, a sandcrawler! The location is unknown as well as whether or not this sandcrawler was used in the war or simply passing by.
The image below shows tracks that still exist today in western Turkey. The tracks have baffled experts for half a century due to the spacing betwen the treads bearing no resemblence to any known vehicle. Perhaps this is further evidence of the existence of sandcrawlers... and possibly, Jawas!
