Dave Neuhardt kindly shared scans of a very fragile printed program from the Opera House. As far as when the program was presented, Dave had this to say: “I didn’t see a year anywhere, although you might get close by figuring out in which years Thursday, Friday and Saturday fell on those days in November. It would have to be 1890 (which I think is the year the opera house opened) by while the YS Weekly Citizen was still being published. My assumption is that it is late 1890’s, but I didn’t try to match the advertisers to any particular period.”
Several of the advertisers were still in existence on the 1918 hand-drawn map of the business district:
Ridgway Pharmacy (vaguely where the Wine Cellar is now)
H. Dickman, The Tinner (probably south of the Little Art Building)
Thanks to Dave for this snapshot of both the kind of entertainment popular at the time, and the kinds of enterprises supporting the entertainment.
