Walk the talk
I've written before about advertiising innovations from yesteryear. These shoes are from the late 1880s. You can view their patent application here.
They're the advertising equivalent of treading on dog shit and walking it through the house as they print advertising messages on the pavement as you walk.
I find it hard to believe that people were thinking of stuff like this 120 years or more ago. Especially when you consider that back then TV or radio hadn't even been invented.
