The title abstract, while difficult at times to read, tells me that the building started as a part of the Illinois theatre.  It was a bar owned by the Rock Island Brewing Company connected to the theatre.

In 1919, Kalina Furs remodeled and moved in, buying the building in 1923.  Not only did they sell fur coats and stoles, they manufactured them on site as well.  They built 3 vaults into the existing structure and added a 4th, three story vault on to the back of the building  to offer summer fur storage for their customers. In 1930 or so, the building looked like this.
