3 free-standing panels with built-in transparent money banks in the form of a thermometer encouraged the public to make cash donations to Caritas. The donations went towards helping the homeless in Vienna in the middle of winter.
The eye-catching thermometer on the creative of the campaign caught the public's attention. The clear call-to-action “Donate” encouraged donations. The more money that was added, the higher the temperature of the thermometer appeared to be. The transparent money bank allowed passers-by to see how much was already raised and encouraged them to donate more.
