In the 1930s, during the height of the Art Deco craze, Jewel Food Stores constructed a series of identical stores all across Chicagoland. Many of these buildings, with their distinct glazed white facades, survive today. I've found six to date, but I imagine there are many more.
I can't find the first word about these buildings online; it's only thanks to Jacob at Forgotten Chicago that I even know what they used to be. Even the exhaustive research at Pleasant Family Shopping barely mentions the 1930s style buildings. I can speculate that the white glazed tile appealed to the sense of modernity and hygiene, which was becoming a more common concern at the time.
The little storefront buildings are quite adaptable; they're serving all kinds of purposes today, from clothing and furniture to liquor sales. Several are home to independent ethnic grocers.
