This pic is from a publicity pamphlet for Cleary titled "Ten Reasons Why [to study at Cleary]." I guesstimate that it's from roughly 1890 or so. Here is a view of the main hall where students are engaged in realistic business transactions. Students were given a mock $2,000 with which to start their business. As you can see by the caption, the school prided itself on using such real-life methods as opposed to textbook work. Click for larger image.
