WOW!!! Did I make a HUGE mistake when I put in my first comment, of which I deleted. Here is the correct comment, with updated pinned location. Looking southeast at 100 South Main Street, Mackinaw, Illinois. With First Security Bank across Main Street, the building is in the southwest corner of West Fast Avenue and South Main Street. In my previous comment, and pinned location, I misidentified this as the Masonic Lodge. My mistake.
