circus train

In addition to NG railroading another of my passions is the circus. In another thread the line is used a "tourist circus train". I wonder how many know that the narrow gauge hauled circuses all over CO and northern N Mexico in the late 1880's? I know pictures of such trains are hard to come up with, but I have spent a lot of time at librarys across CO looking at old newspapers and have quite a bit of info. But still no pictures have turned up. HELP.

Uncle Bob told me several years ago that he did not know of any pics, but hopfully some area around.
