As the official advertising mascot of the American Water Works Association since the 1940s, Willing Water was once almost as visible as Reddy Kilowatt in his heyday.
One of the most popular uses of Willing Water was on the ubiquitous "Water At Your Service" logo. It was used all over the country by various water utilities. The logo is still used on Water Department trucks in my town, Sheffield Lake.
Willing Water was featured in his own comic book in 1966, as well as a cookbook that same year. So what happened to Willie since then?
In the 1980s, the American Water Works Association quietly discontinued his use and decided to let the copyright lapse as well. That means that even though Willing Water is now more or less an orphan, water utilities are free to use him as they see fit.
