I've been working on a historical documentation of the Circus World Museum's parades over the years and in particular the Train. By 1973, the CWM had suffered a huge setback in the death of Robert Uihlein, the President of the Jos. Schlitz Brewing Co. who had so very generously poured tons of money into the CWM train and wagon Collections for the last ten years.
Somewhere along the line, the thoughts that the parade would roll again in 1974 got started with some printing occurring. Needless to say, I was sure surprised when I found this on eBay last week.
