Here's a factoid from the laundromat industry: What's known as "Norge Balls" were developed by a national chain of laundromats called Norge Village Cleaners based out of Chicago in the early 1960's. The Plastic, polka-dotted ball signs remind many of Wonder Bread wrappers, and revolved on poles or roofs with lighting inside. This one in Tucson, Arizona still stands at Dean's Village Cleaners, which opened in 1961. Image by Jeroen and Maggie Boersma
