This is one of my favorite "odd" photos. This is an Evansville & Terre Haute / Frisco loco. Did the Frisco control this road? I know the C&EI took control of it in 1911. Were there other small roads with locos marked for both roads? I know the C&EI was marked with both.
Perhaps there are some clues in this article: http://www.ceihs.org/historians_main_1.html "Frisco control (1902-1913) gave...C&EI steam power its handsome Frisco-like appearance."
