In the works from the series “Interact with Someone unknown”, an unsigned work, such as graffiti from public spaces, is the basis of the work. Through the finished photo image, an attempt is then made to establish contact with the artist of the original and to make him a known artist. Chris Uphues is one of the artists contacted in this way. Chris lives in Brooklyn and is known as “the heart artist” because he leaves his heart graffiti on public spaces in New York. One of them was taken by us and used as a basis for some photo images. The result was posted back on the same NY-Queens construction fence where we found it, two months later, with a QR code containing a request to get in touch. After the subsequent contact, the idea for a joint project was born – “Heart Attack”.
