"Steuerfreies Einkommen" (Tax-Free Income) grew directly out of the long-time project "Bilder von der Straße" (Pictures from the Street). Looking out for abandonded photographs in the streets, it was inevitable that I found other things too such as money. Usually, this would be in the form of petty cash and small coins but occasionally, I would find a banknote. For many years I simply picked all these up and put them in my wallet. In 2011, before the completion of "Bilder von der Straße", I began to make annual inventories of the found money. These are published in book form.
The project's accounting is public. Tax-free income accummulated in 2012:
4.49 € + 1.00 SFr + 0.04 Zł + 1.67 $ (US) + 0.01 $ (Can) – Total: 6.34 €
