Small paintings (4.5 x 4.5 cm) hang
in public space, freely accessible to everyone.
A project to encourage free possession of art,
because all works can easily be taken along.
However, it is not really so completely free, since
someone always has to pay according to economic principles.
Because the sentence:
"There ain't no such thing as a free lunch" (TANSTAAFL),
which means there is nothing for free (see Wikipedia).
However, in this case it is not necessarily the artist who pays
for the painting he has painted and delivered free of charge.
Reduced VAT, tax-saving write-offs, direct and indirect state
subsidies, subsidised studios, fees from public institutions
and so on allow all artists to work on their art undisturbed.
In this respect, the allegedly free works are already paid for
by society as a whole, and thus also proportionately by the
finder of the picture.
Therefore, this project also serves to give back to society
a little of the public funds I also use.

Thank you very much for that
and enjoy the painting - 
or have fun searching.
