The mural "Bridge of Thoughts to 'Blauer Klaus'" commemorates the oldest harbor floating crane in the state of Bremen, the SK 16, located in the Old Harbor of Bremerhaven. Built in 1923 at the AG Weser shipyard, the crane is positioned near its original site at the former turning basin of the Overseas Harbor.

The abstracted silhouette of the crane’s head, known as "Blauer Klaus," symbolizes the connection between the historic and contemporary harbor activities. This artwork serves as a bridge of thoughts, linking the past and present of the harbor.
