This was the first flyer ever designed to be stuck to a car's boot, not its windscreen. Specially-printed strips of paper let money flow from car boots across major German cities.

The flyer instantly communicated Postbank Private Credit’s benefits.

And at the same time it turned an ordinary flyer into high-impact guerrilla-marketing. The banknote flyer looked convincingly real when first seen by the car owners and it caused a lot of surprised delight. The flyer's average rate of return was 21%.
