On this day, 37 years ago, on December 7, 1988 (October 29, 1988, the world's largest paint painting project to be painted on the outer wall of a floating dock began. On December 7, 1988, the world's largest paint painting will be painted. The huge project on the outer wall of the shipyard's floating dock officially began. The creator and chief designer of the painting is 48-year-old painter Roland Stegman. He spent a year and a half preparing, carefully reviewing a large number of historical materials about the Port of Hamburg and visiting many historical objects in the museum. A sketch was then drawn to describe the changes in the Port of Hamburg since 1189, ranging from the oldest fiber-drawing wooden boats to modern container ships. Stegman first scaled up the sketch and drew it on the dock wall. He hired eight highly skilled painters to paint in the specified colors. The giant painting took a full 5 months to complete, consuming a total of 5000 liters of various colors of paint. The expenses are sponsored by a number of public and private companies. This world's largest painted painting is 250 meters long, 13.5 meters wide, and has a total area of 3375 meters. It was created to commemorate the 800th anniversary of the opening of the Port of Hamburg. The entire painting was painted on the outer wall of floating dock No. 10 at a shipyard on the Elbe River in the Port of Hamburg.
