Schmitz and Gretencort
Nice 1912 postcard here, which advertises the Schmitz and Gretencort department store (click on either image for the full-sized version). Interesting to note that the "holiday sale of questionable relevance" concept ("4th of July Home Coming Sale") is by no means a modern-day development. I've seen ephemera from this store before and had assumed it was a Joliet company, but based on the ordering of the locations listed on the back, it appears to have been an Aurora company with a Joliet branch. This building is still standing, but the interior has been fully modernized and this view is now long gone.
