Ink, enamel on paper on linen, Unframed.

As the title suggests (a tondo is a Renaissance term for a circular work of art), this artwork is part of a series with a circular form without edges. 

It is made of paper painted with ink and enamel, then glued on a canvas. 

Its round shape confers it a multidimensional character, since it can be hanged, in line with the artist's intention, in four directions.

As often with Kröner's work, poetry and beauty emerge from the subtle combination of a relatively rigid framework (here, the vertical and horizontal grey lines), with more random and lively colour marks.
