HELMUT KOLLER Studio
A note to collectors
In preparation of compiling a catalogue raisonné of my work, I would like all owners of my original paintings and artworks to contact Helmut Koller Studio. (Please use the link below).
A Certificate of Authenticity is included with every original Koller animal painting.
In case the painting(s) you own is/are not accompanied by the artist's issued CoA, please contact the studio.
