The trophy is made of two parts: a cube greywacke and a mirror-glass ball. Contrast, but also unity.
One day when I walked from the Rhine to the old inner city, I found out that in Cologne greywacke is almost everywhere: from the Roman city wall to the paving slabs. Greywacke is actually a cultural symbol of Cologne.
When the winner takes this trophy, he/she touches the old stone from Cologne, and sees his/her own face, as it is reflected in the glass ball. Honor, pride, style, elegance, culture … The Cologne memory is a wonderful recalling.
