When I first got my newspaper machine, a cast iron bank from Liberty Collectibles, it was emblazoned with logos of Shell Oil. It looked like this:
I printed out some generic graphics, collected from royalty-free, online clipart, to cover the Shell logos. I made up my own slogans, except for “We’ve got issues,” which is the 103% real slogan of our local weekly paper Seven Days. I laminated the graphics with clear packing tape and glued them on the machine. It now looks like a generic dispenser of a free newspaper, appropriate for many English-speaking locales.
